Heavy plate LR grade A passage ship steel 12cm size

After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, LR grade A passage ship steel 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 LR grade A passage ship steel steel and 542,000 tons of steel.The main function of boron in LR grade A passage ship steel and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum For this purpose, the boron content is generally regulated in the range of 0001% - 0005% It can replace 16% nickel, 03% chromium or 02% molybdenum It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron,LR grade A passage ship steel., Q355GNH weather resistant steel plate is one of our main product, it is belong to the weather resistant steel plate. We can supply the different sizes of Q355GNH weather resistant steel plate.
