Our company is a specialized technical support and after-sales service organization - customer service center. At the same time, we have provided excellent technical EN10025-4 S275M steel plate personnel and strong technical support for our company, and cultivated an excellent after-sales team for our company. Our company will appoint a full-time service manager to be responsible for the unified coordination of technical support and EN10025-4 S275M steel plate after-sales service of the project.

The steel grades EN10025-4 S275M steel plate of thick steel plate are basically the same as those of thin steel plate. In terms of steel types, in addition to the bridge steel plate, boiler steel plate, automobile manufacturing steel plate, pressure vessel steel plate and multi-layer high-pressure vessel steel plate, some kinds of EN10025-4 S275M steel plate steel plates, such as automobile girder steel plate (2.5-10 mm thick), checkered steel plate (2.5-8 mm thick), stainless steel plate, heat-resistant steel plate, etc., are crossed with the thin plate.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for EN10025-4 S275M steel plate, 42CrMo steel is quenching and tempering.

EN10025-4 S275M steel plate, low alloy high strength steel can meet the requirements of various structures (such as large bridges, pressure vessels, ships, etc.) in engineering. At the same time, it is required to reduce the weight of the structure, improve the reliability and save materials and resources. Low alloy high strength steel is mainly used to manufacture various engineering structures with high strength requirements, such as bridges, ships, vehicles, high pressure vessels, oil and gas pipelines, large steel structures, etc. Because low alloy high strength steel can obtain high strength without complicated treatment process or even heat treatment, the quality of engineering structure is greatly reduced. Therefore, low alloy high strength steel is commonly used to replace the general carbon structural steel.

As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality EN10025-4 S275M steel plate products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.

The company will rely on its good reputation, excellent hot-rolled plates, steel pipes, steel structure products, and intimate EN10025-4 S275M steel plate after-sales service to customers. I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! The company sincerely hopes to establish a long-term cooperative relationship with them, mutual benefit and common development. Welcome to come and visit our EN10025-4 S275M steel plate steel mill.
