Simple introduction about Stainless steel sheet

The surface of the stainless steel sheet is smooth, has high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. It is an alloy steel that is not easily rusted. The stainless steel plate refers to a steel plate that is resistant to corrosion by weak media such as atmosphere, steam, and water, and the acid-resistant steel plate refers to a steel plate that is resistant to corrosion by chemical etching agents such as acid, alkali, and salt.

Simple introduction about Stainless steel sheet

Corrosion resistance

The stainless steel sheet has the ability to withstand general corrosion similar to the unstable nichrome 304. Prolonged heating in the temperature range of chromium carbide may affect alloys 321 and 347 in harsh corrosive media. Mainly used in high temperature applications, high temperature applications require strong sensitization of materials to prevent intergranular corrosion at lower temperatures.

High temperature oxidation resistance

Stainless steel plates have high temperature oxidation resistance, but the oxidation rate is affected by inherent factors such as the exposed environment and product morphology.

Physical properties

The total heat transfer coefficient of the metal depends on other factors, in addition to the thermal conductivity of the metal. In most cases, the film’s heat dissipation coefficient, scale and metal surface condition. Stainless steel keeps the surface clean and tidy, so its heat transfer is better than other metals with higher thermal conductivity. Liaocheng Suntory Stainless Steel provides technical standards for stainless steel plates. High-strength stainless steel plates with excellent corrosion resistance, bending processability and weld site toughness, and excellent stamping performance of welded parts.

Specifically, it contains C: 0.02% or less, N: 0.02% or less, Cr: 11% or more and less than 17%, and an appropriate content of Si, Mn, P, S, Al, Ni, and satisfies 12 ≤ Cr Mo 1.5Si ≤ 17, 1 ≤ Ni 30 (CN) 0.5 (Mn Cu) ≤ 4, Cr 0.5 (Ni Cu) 3.3Mo ≥ 16.0, 0.006 ≤ CN ≤ 0.030 stainless steel plate is heated to 850 ~ 1250 ° C, and then carried out at 1 ° C / s The above heat treatment for cooling rate cooling. Thus, it can be a structure containing a martensite having a volume fraction of 12% or more, a high strength of 730 MPa or more, corrosion resistance, bending workability, and a high-strength stainless steel sheet excellent in weld heat-affected zone toughness. By using Mo, B, etc., the press working property of the welded portion can be remarkably improved.

The flame of oxygen plus gas cannot cut stainless steel because the stainless steel is not easily oxidized.

5CM thick stainless steel plates are machined with special cutting tools, such as:

(1) Plasma arc cutting

(2) Hydraulic sawing machine

(3) grinding disc

(4) Large wattage of Laser Cutting machine (laser cutting machine)

(5) Wire Cutting machine.

(6) Human hand saw

(7) High pressure water jet cutting

The selection of stainless steel plates should consider the operating conditions, such as manual operation or automatic operation, the performance and type of the hot press, and the quality requirements of the pressed materials such as hardness and gloss. Also consider the economic accounting, each time a new polished steel plate, the number of times to produce a slow quality decorative board.1 inch square steel tubing

In addition, when selecting the reasonable thickness of the steel plate, the time, quality and rigidity of the steel plate should be considered, and the strength requirements of the plate under pressure should be considered; the heat conduction performance; the pressure distribution, the format of the pressure plate.

If the thickness of the steel plate is not enough, it is easy to bend, which will affect the production of decorative panels. If the thickness is too large, the steel plate is too heavy, which not only increases the cost of the steel plate, but also brings difficulty in operation. At the same time, the remaining amount of stainless steel plate processing or use should be considered. The thickness of the copper plate is not uniform, but the thickness of the same steel plate is to be as uniform as possible. Generally, the medium-sized saw blade has a thickness tolerance of 0.05-o.15 mm. If the requirements are too strict, the grinding costs will also increase. Generally, it is a steel plate with large tensile strength and hardness, and the greater the resistance to mechanical damage, the longer the durability of use, but the processing cost of the grinding boring is also relatively high.

Pipeline purchased steel

As modern procedures and applications have developed, industry associations have created exceptional arrangements and determinations for the pipe bound for administration in those segments.Galvanized Steel Coil Manufacturer

There’s heaps of cover among the associations’ distributed specs, and likely loads of disarray too.

Pipeline purchased steel


Purchasers can improve their obtaining background by becoming familiar with how evaluations of steel are assigned for channeling and by seeing all the data that ought to be incorporated on a buy request.


Both the American Society of Testing and Methods (ASTM) and the American Society of Mechanical Engineers (ASME) distribute funneling specs. ASTM and ASME pipe assignments for evaluations of steel are fundamentally the same as.

For instance, A106 B is a spec distributed by ASTM (the ASME spec would be SA106 B). The “An” assigns a ferrous material. ‘106’ is a self-assertive number that assigns it as a consistent carbon steel pipe appropriate for high-temperature administration. At that point, grades, (for example, A, B or C) are doled out that show certain qualities of the steel dependent on contrasts in its concoction cosmetics and mechanical properties.

Pipe sizes are depicted by utilizing a pipe outline (ANSI/ASME B36.10 and API5L) that incorporates the outside distance across and divider thickness. The outside distance across can be alluded by the ostensible pipe measure (NPS) or the real measurement in inches and the divider by expressing the timetable or the genuine thickness in inches.

Note that while ASTM and ASME specs are to a great extent indistinguishable, a significant distinction is that pipe implied for use in weight frameworks in some cases requires extraordinary or extra quality tests before it agrees to the ASME standard.ppgi coils manufacturer

American Piping Products stocks a full scope of A/SA106 and A/SA 53 carbon steel pipe.


Pipe for use in the oil and gas industry are ordered by the American Petroleum Institute’s (API) framework.

Programming interface 5L is the most widely recognized standard to which line pipe in the oil and flammable gas industry is appraised. Since that is just a standard, extra data is expected to guarantee buy requests are executed precisely.

Programming interface 5L pipe is separated into PSL1 and PSL2 conveyance conditions; those conditions are additionally separated into pipe grades, for example Evaluation B, X42, X52, X65, and so forth. Purchasers ought to incorporate the blend of the general standard, the conveyance condition and the evaluation for the API5L pipe they need.


The American Iron and Steel Institute (AISI) and the Society of Automotive Engineers (SAE) share a numbering framework to group steels. AISI/SAE assignments just depict the concoction cosmetics of a steel. They do exclude fabricating, heat treating or testing data.

Utilizing 1020 steel for instance, the principal digit communicates the steel as a plain carbon steel. The subsequent digit demonstrates there are no additional compounds. The last two digits show the steel has around 0.20 percent carbon content.

For another model, a prevalent steel in the channeling business is 4130. The ’41’ shows the steel contains chromium and molybdenum combinations. The ’30’ demonstrates the steel has around 0.30 percent carbon content.

Once more, AISI/SAE assignments just arrange steels. For instance, a purchaser who says, “I need 100 feet of 4130” has not given enough data. The purchaser additionally needs to note explicit creation and testing data found in an ASTM or ASME spec to get precisely the pipe they need.

Technology has played an important role in the steel industry

In the past 150 years, technology has played an important role in the steel industry. It may be one of the most affected industries in the United States. This matter is caused by many reasons.stainless steel sheet

This can be traced back to the industrial revolution of the 19th century. As the workplace security needs grow, the steel industry needs new technologies. Steel demand is also high, requiring more efficient, timely and cost-effective production methods.

Technology has played an important role in the steel industry

Artificial intelligence in the steel industry

It is important to understand the problems facing the steel industry in terms of high-tech advancement.

One of the advances has emerged in other industries such as healthcare, banking and finance. This technology is called artificial intelligence (AI). The future impact of artificial intelligence has not been seen as the end result of its use.

Growing fear of technology:

In the steel industry, people are worried that robots will replace humans and take over their jobs. However, the steel industry relies on solutions and answers to workplace safety, efficiency and cost-effectiveness issues.

Unless the industry is reluctant to adopt today’s most advanced technology as its global competitor, it’s easy to see how this will lead to a downturn in the industry.steel wire suppliers

Technology has already had an impact on integrated steel mills and small steel mills. Most steel processes have relied on robots in blast furnaces, boilers and ovens to complete the work of steel mill workers. These robots have become the primary method of workplace safety and efficiency.

What does robot technology mean for the steel industry?

AI relies on computer-to-computer data creation. This is also known as peer-to-peer computer technology and may have the effect of reducing human input to these computers.

In AI, part of the technology includes “blockchain”, encrypted, decentralized, and time-stamped data histories.

As a result, this new technology has created jobs in certain industries, rather than creating unemployment. It is important to remember that AI and blockchain techniques are created by humans.

In the steel industry, robots cannot take over jobs that only humans can do. The method of producing steel has been in a state of change.

Can robots replace humans?

In fact, technology always replaces the work of human beings. The new question that emerges today is whether AI or robots will replace the manpower work in the steel industry. These robots need to perform production calculations, efficiency ratings, and even engineering.

To address these concerns, the Massachusetts Institute of Technology (MIT) provides a study on whether robots or technology can replace humans.

Interestingly, the study is not entirely sure whether there will be high unemployment. Many people believe that robots in the engineering process will reduce work injuries and anomalies. However, we still need human maintenance, decision making and many other aspects.

The study cites several other sources that seem to be unable to reach consensus, such as Oxford Research, the McKinsey Report, and the OECD (Organization for Economic Co-operation and Development) study.

Research by the Massachusetts Institute of Technology shows that depending on the type of industry, robots can cost millions to billions of jobs. However, in the end, each company maintains the relevant industry of its main competitors to gain market share.

Future steel industry:

It is easy to see how the steel industry will develop in the future. Steel work will be less personal and involve more human wisdom and knowledge.

The future of the steel and metals industry may change in three ways:

1.Virtual Reality (VR) enables virtual facility operations to create new business models.

2.Blockchains enable proven material tracking, such as recycling steel.Galvanized Steel Tube Suppliers

3.Machine learning simplifies the production process while simplifying the steel manufacturing business.

Why are the same shape of galvanized steel pipes at different prices

The shape of galvanized steel pipe is generally round and square, but there is no other shape of galvanized steel pipe. The galvanized steel pipe is divided into hot-dip galvanized steel pipe and cold-galvanized steel pipe, whether it is round steel pipe or square steel pipe. One feature is that it can be galvanized. Then why the shape of the galvanized steel pipe is the same, but the following is a small series for everyone to explain.square steel tubing

As one of the galvanized steel pipes, the galvanized pipe is a very practical steel. This new steel is different from the previous steel, and its performance is stronger. The steel can be cold-rolled or hot-rolled. It is made into the galvanized steel strip used now. The galvanized steel pipe is galvanized after the hot rolling process, and the hot galvanizing coating is uniform, which can extend the service life of the steel plate, which also makes the galvanized steel pipe have Very good corrosion resistance.

Why are the same shape of galvanized steel pipes at different prices

There is generally a difference in quality between galvanized steel pipes. The price of steel pipes sold by different steel pipe manufacturers will also be different. Secondly, the galvanized steel pipe process will be customized. The galvanized steel pipes will be customized according to national standards, although cold-galvanized steel pipes and hot-dip plating.The shape of the zinc pipe is not much different, but the hot-dip galvanized steel pipe is thicker in the process, so the price is higher.

There are many galvanized steel pipe manufacturers that can order on the Internet, and can also get in touch with the customer’s customer service. We can simply understand what the other party’s offer is, why there is such a quote, and so on. As long as it can meet our requirements, you can choose to compare samples, you can know the quality of the steel pipe, the cost performance has always been the user’s most concerned issue, so ordering steel pipe on the Internet can save customers a lot of time.welded pipe manufacturers

Secondly, there is the phenomenon of agents. There is a certain gap between the direct sales of galvanized steel pipe manufacturers and agents. The purchase price of general agents will be very low, but the price of selling will be a lot. The phenomenon of middlemen making the difference is in each. The industry exists. If you want low price and quality assurance, please go directly to the steel pipe manufacturers to buy. Today, why is the galvanized steel pipe with the same price but different prices? The content is here, I hope to help everyone.

Hot Galvanized Seamless steel pipe

The seamless steel pipe is a circular, square, rectangular steel with a hollow section and no seams around it. The seamless steel pipe is a steel ingot or a seamless steel pipe which is a circular, square, rectangular steel having a hollow section and no seam at the periphery. The seamless steel pipe is formed by perforating a steel ingot or a solid tube blank, and then hot rolled, cold rolled or cold drawn. The seamless steel pipe has a hollow section and is used as a pipe for conveying fluid. Compared with a solid steel such as round steel, the steel pipe is light in weight when it has the same bending and torsional strength, and is an economical section steel, which is widely used in manufacturing structures. Parts and mechanical parts, such as oil drill pipes, automotive drive shafts, bicycle frames, and steel scaffolding used in construction.

The solid tube blank is perforated into a capillary tube and then formed by hot rolling, cold rolling or cold drawing. The seamless steel pipe has a hollow section and is used as a pipe for conveying fluid. Compared with a solid steel such as round steel, the steel pipe is light in weight when it has the same bending and torsional strength, and is an economical section steel, which is widely used in manufacturing structures. Parts and mechanical parts, such as oil drill pipes, automotive drive shafts, bicycle frames, and steel scaffolding used in construction.

Seamless steel pipe

The specifications of seamless steel pipes are usually expressed by the outer diameter * wall thickness (unit: mm). Such as: outer diameter 30mm inner hole 20mm wall thickness is 5mm Generally speaking: Φ30*5. According to the production method, seamless steel tubes can be divided into two categories: hot-rolled seamless steel tubes and cold-rolled (dial) seamless steel tubes. Hot-rolled seamless steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes. Cold-rolled (dial) seamless steel pipe in addition to general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, other steel pipes, including precision steel pipe, carbon thin-walled steel pipe, alloy thin Wall steel pipe, stainless steel thin-walled steel pipe, special-shaped steel pipe, etc. The outer diameter of hot-rolled seamless pipe is generally larger than 32mm, the wall thickness is 2.5-75mm, the outer diameter of cold-rolled seamless steel pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of thin-walled pipe can be 5mm, the wall thickness is less than 0.25mm, cold Rolling is more accurate than hot rolling. In pipeline engineering, hot-rolled pipes are often used when the pipe diameter exceeds 57 mm, and cold drawn (rolled) pipes are often used when the pipe diameter is less than 57 mm.Galvanized Steel Tube

Generally, the seamless steel pipe is made of high-quality carbon steel such as 10#, 20#, 30#, 35#, 45# or low-alloy structural steel such as 16Mn or 5MnV or alloy structural steel such as 40Cr, 30CrMnSi, 45Mn2 and 40MnB. Cold rolled into. Seamless pipes made of low carbon steel such as 10# and 20# are mainly used for fluid conveying pipes. Seamless tubes made of medium carbon steel such as 45# and 40Cr are usually used to make mechanical parts, such as parts for automobiles and tractors. Generally, seamless steel pipes are required to ensure strength and carry out flattening tests. The hot rolled steel pipe is delivered in a hot rolled state or a heat treated state; the cold rolling is delivered in a heat treated state.welded pipe manufacturers

Hot rolling, as the name suggests, has a high temperature of the rolled piece, so the deformation resistance is small and a large amount of deformation can be achieved. Taking the rolling of the steel sheet as an example, the thickness of the continuous casting blank is about 230 mm, and after rough rolling and finish rolling, the final thickness is 1 to 20 mm. At the same time, due to the small width-to-thickness ratio of the steel plate, the dimensional accuracy requirement is relatively low, and the shape problem is not easy to occur, and the convexity is mainly controlled. For the requirements of the organization, it is generally achieved by controlled rolling and controlled cooling, that is, controlling the rolling temperature, finish rolling temperature and crimping temperature of the finishing rolling to control the microstructure and mechanical properties of the strip.

Welded steel pipe

A welded steel pipe is a steel pipe which is welded and formed by a steel strip or a steel plate and deformed into a circular shape or a square shape, and has a joint on the surface. The blank used for welded steel pipes is steel or strip.welded pipe manufacturers

When the Ni-containing welded steel pipe contains Ni, the corrosion resistance is strong in an acidic environment. In the environment containing sulfuric acid or hydrochloric acid, the higher the content of Ni in the T-welded steel pipe, the stronger the corrosion resistance. In the general environment, it is only necessary to add Cr to the T-welded steel pipe to prevent corrosion. Poor steel edge conditions are another important cause of misalignment. The effect of mass flow, heat flux density and structural parameters (ratio of the diameter of the spiral curvature and the diameter of the T-welded steel pipe Dc/D) on the saturated bubble boiling heat transfer coefficient in the vertical spiral tube.

welded pipe manufacturers

In the production of T-welded steel pipes, there are many factors influencing the wrong side. In the production practice, the steel pipe is often downgraded by the dry and wrong side. Therefore, it is necessary to analyze the causes of the wrong side of spiral steel pipe and its preventive measures.

Due to the poor shape and dimensional accuracy of the uncut edge of the steel strip, it is easy to cause the steel strip to bend hard and cause a wrong edge. Simulation parameters range: vertical pipe: pipe diameter D=lOmm, pipe length L=660mm; three vertical T-welded steel pipes: pipe diameter D=10mm, the ratio of the curvature diameter of the T-welded steel pipe to the diameter of the spiral pipe is Dc /D=15,20,25, spiral pitch Pt=20mm, tube length L=503mm, L=660mm, L=817MM. Mass flow rate G=200~400Kg/(m’2·s), heat flux density q=5~15KW/m’2, saturation pressure p, saturation=0.414880MPa, saturation temperature T, saturation=283.15K.

The US Withdraw Troops from Syrian (I)

On the 19th, local time, US President Trump declared that the terrorist organization “Islamic State” has been defeated and the US military will withdraw from Syria. The White House also confirmed the news. Seven years, is the suffering in Syria over? In this scarred country, will the war be extinguished or will it continue to burn?

Damascus weeping blood: 7 years situation complex evolution

The “Arab Spring” spread to Syria in January 2011, and anti-government demonstrations escalated in March and gradually evolved into armed conflict.Metal Coils

With the support of Western countries and some Sunni Middle Eastern countries, the Syrian opposition forces were armed and armed with the Bashar government, eventually becoming a civil war and continuing to this day. After 2012, the Syrian civil war became hot, and the extremist organization “Islamic State” rose up. In 2014, the United States led the international coalition forces to intervene on the grounds of combating the “Islamic State.” The Syrian opposition also gradually seized important positions in cities such as Aleppo, and the overwhelming superiority of government forces in the early days of the war no longer existed. In those years, a large number of refugees left their homes and fled their borders, forming a wave of refugees that caught the attention of the world.
