How to identify inferior S355J2W railway steel

The company's operation is based on the principle of "quality for survival, reputation for development". In terms of management, we adhere to the principle of people-oriented, service-oriented and customer-oriented. All staff of the company have the courage to open up, unite and forge ahead, and work hard to grasp the good situation of global economic development, actively strengthen communication with outstanding enterprises in the S355J2W railway steel industry, keep pace with the times, and move towards a new course!

S355J0 steel is a low alloy structural steel. We can supply S355J0 structural steel plates up to 400mm, with a minimum yield strength 355MPa when plate thickness less than 16mm, min. yield strength 345MPa when plate thickness range 16mm to 40mm. Without any special rolling or heat treatment for S355J0 steel plate and sheet, S355J2W railway steel, the abbreviated designation of this delivery condition shall be AR (As rolled).

NM400 alloy steel plate is a kind of wear-resistant steel plate. NM—The first letter of the Chinese pinyin 400 of the characters “resistant” and “grind” for wear resistance is the HB value of the Brinell hardness value. NM400 alloy plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other product parts. Excavator, loader, bulldozer bucket plate, blade, side blade, blade.

Corrosion resistance of stainless steel mainly owes to the formation of a very thin, adhesive and translucent chromium oxide film on the surface of stainless steel. Once the film is damaged, the chromium in the stainless steel will react with oxygen in the atmosphere to restore the film quickly. At the same time, the mechanical damage can also generate a protective film quickly to prevent the S355J2W railway steel, stainless steel from corrosion.

Difference between Q235A steel and Q235B steel plates: in the national standard GB700, the difference between S355J2W railway steel, Q235A steel and Q235B steel plates is mainly in the carbon content. In addition, Q235A steel plate does not do impact test, while Q235B Q235B steel plates need normal temperature impact test, V-notch. Relatively speaking, the mechanical properties of Q235B steel plates are better than that of Q235A steel plate.

Over the years, the company has maintained long-term stable business relationships with major domestic steel mills and foreign steel companies. The company's main boiler and pressure vessel steel plates, low alloy high-strength steel plates, wear-resistant steel plates, corrosion-resistant steel plates, S355J2W railway steel bridge steel plates , strucural teel plates, steel plates for alloy structures, mold steel plates, steel plates for shipbuilding and production platforms, composite steel plates, steel plates for oil and gas pipelines. Welcome to come China and visit our S355J2W railway steel production line.
