Do you know the Q295NH railway steel standard material

Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional Q295NH railway steel production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of Q295NH railway steel leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.

RAEX400 steel is a hardened wear-resistant steel material with an average grade of 400HBW and a Brinell hardness. The microstructure of this wear-resistant steel is a martensite structure, which can ensure the high hardness and tensile hardness of the steel plate. The hardness of RAEX400 is 2.5 times that of S355 structural steel, Q295NH railway steel. Despite its high hardness and high strength, RAEX400 steel can be formed by free bending or hemming, and has good weldability.

In the face of domestic and foreign steel situation, based on the advantages of production and inventory, we have established our own processing center, and our manufacturing includes different types. Steel Q295NH railway steel surface treatment - such as steel pretreatment (shot peening and shop primer), steel galvanizing; steel structure processing - such as cutting, drilling, milling, turning, bending, welding, etc.

Temperature has a great influence on the strength of the material, Q295NH railway steel. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.

Main Q295NH railway steel production plants: Wugang, Baosteel, Laiwu Steel, Angang, Baotou Steel, BBN Steel, Katalor Industry
Pressure vessel plates are used to manufacture steel plates for steam boilers, pressure vessels and other pressure vessel structures. Because this kind of steel plate is subjected to certain air pressure and water pressure, and the use environment of different temperatures, such as high, medium and low temperature, etc., the requirements for this kind of steel plate are relatively strict.

The company specializes in hot rolled plates producing, steel plate processing, steel plates cutting, carbon steel plate weldding and exporting of wide and thick steel plates. BBN company has high-quality CNC Q295NH railway steel steel plate cutting processing equipment, professional technical personnel, and supporting marketing and after-sales service system. Sincerely welcome new and old customers to visit our company, BBBN company will always be your reliable choice.

We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".
