Hot rolled hardox 400 steel equivalent welding process

St52-3 steel, HARDOX 400 steel equivalent is low alloy high strength steel. The main characteristics of St52-3 steel are high tensile strength and yield point. St52-3 steel is used in civil construction, underground engineering, bridge structure, ocean structure, container manufacturing, automobile and machine manufacturing. Based on the principle of quality oriented, the company has established a perfect quality standard inspection system to provide customers with high-quality and low-cost steel products and after-sales services, which has been supported and praised by new and old users from all walks of life.

Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and HARDOX 400 steel equivalent resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, HARDOX 400 steel equivalent new materials, and promotes the competition of enterprises Struggle.

There is an inherent difference between the cold forming properties of low-alloy high-strength steel and carbon structural steel. First of all, a certain amount of permanent deformation of low-alloy high-strength steel requires greater force than HARDOX 400 steel equivalent, carbon structural steel of the same size. Second, when low-alloy high-strength steel is formed, a slightly larger allowable amount for springback should be given. According to experience, unless the low-alloy high-strength steel is processed to control the shape of inclusions, it is necessary to use a larger bending radius than carbon structural steel during cold forming.

Our strutural steel plates are not attacked easily by the chemicals in harsh weather. They are a hard, strong, and durable product. Their characteristics are tested through tests. We perform hardness, pmi, micro, chemical, mechanical, macro, ultrasonic test and more. We pack carbon steel plates, HARDOX 400 steel equivalent, hot rolled plates, structural steel sheets safely to maintain their good performance so that they serve longer than usual.

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 HARDOX 400 steel equivalent 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.
