Weathering steel has good resistance to atmospheric corrosion. Although the initial investment cost of weathering steel is slightly higher than that of ordinary carbon steel. Compared with methods such as spraying anticorrosive coating on the surface of ordinary carbon steel, the later maintenance costs of ordinary carbon steel are weathering steel. 1.5-2 times. Therefore, 30MnB5 chemical requirements weathering steel can reduce environmental pollution and is a key promotion technology for energy saving and emission reduction. Most domestic weathering steels are painted and used, and their original intentions of no-painting and "rust prevention" have not been exerted to a greater extent.
