High-strength steel plates have the following characteristics. First, the strength is high, the bearing capacity is very good, and it is not easy to break. Second, compared with other steel plates under the same strength requirements, high-strength steel plates are lighter and thinner, which can effectively reduce the weight of structures. Third, the A36 ms sheet, high-strength steel plates are required to be safe and reliable, able to withstand complete disasters such as water, fire, earthquake, storm, etc., to protect people's safety.
After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, A36 ms sheet tubes, wires, belts, and profiles have a certain scale, including magnetic, elastic, expanded, bimetal and other precision alloy materials for national defense and electronics industries. In 1982, these plants produced 364,000 tons of A36 ms sheet steel and 542,000 tons of steel.
Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as A36 ms sheet. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel containing magnesium are fine and uniform. When Mg content is 0.002% - 0.003%, the tensile strength and yield strength of the steel increase by more than 5%, and the plasticity remains basically unchanged.
Hot rolled steel for cold forming can be divided into general purpose, stamping, deep drawing and ultra deep drawing according to its use. Common grades include A36 ms sheet, DD11, DD12, SPHC, SPHD, SPHE steel. Hot-rolled steel for cold forming produced by our company uses low-carbon component, and has good stamping performance, welding performance and high dimensional accuracy. This material is widely used in various cold forming industries.
