BBN SM400B grade steel steel equivalent grades

Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.

The company breaks through the production limit of ultra-wide pressure vessel steel plates and can provide ultra-wide CrMo steel plates for pressure vessels over 5 meters. This breakthrough not only upgrades the manufacturing capacity of ultra-wide SM400B grade steel steel plates, but also greatly improves the safety of petrochemical refining pipelines, promotes the development of petrochemical industry equipment, and promotes the high-end manufacturing of ultra-wide pressure vessel CrMo steel plates.

The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of SM400B grade steel, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.

Facing the new situation and facing new goals, the company revolves around the sixteen-character development policy of “prioritizing production preservation, society-oriented, market operation, and brand creation and efficiency”. Layout the country in accordance with the modern logistics model, and accelerate the establishment of a modern integrated steel enterprise integrating steel storage, transportation, processing, and distribution.

The company has passed ISO quality management system certification, domestic advanced production technology, and high product batch stability. Selected materials, the source controls every quality link to ensure SM400B grade steel product high quality. Use automated, scientific and systematic manufacturing processes to meet the different needs of customers. Become an excellent domestic steel plate manufacturer, serving customers all over the world.
