Main factors affecting EN steel grade S420N material price

Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and EN steel grade S420N material 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, EN steel grade S420N material new materials, and promotes the competition of enterprises Struggle.

The service temperature of high pressure seamless steel pipe is below 450 ℃, and the domestic pipes are mainly made of EN steel grade S420N material, No.10 and No.20 carbon steel hot-rolled pipes or cold drawn pipes. High pressure seamless steel pipe is often used in high temperature and high pressure conditions. Under the action of high temperature flue gas and water vapor, the pipe will be oxidized and corroded. The steel pipe is required to have high endurance strength, high oxidation resistance and corrosion resistance, and good structure stability.

Wear resistant steel plate has high wear resistance and good impact performance. It can be cut, bent, welded, etc. This material EN steel grade S420N material can be connected with other structures by welding, plug welding, bolt connection, etc. Wear resistant steel plate has the advantages of saving time and convenience in the process of maintenance. It is widely used in metallurgy, coal, cement, electric power, mining, building materials and other industries. Compared with other materials, wear resistant steel plate has a high cost performance, and has been favored by more and more industries.

At the initial stage of corrosion, the rust layer on the surface of weathering steel is denser than that of carbon steel, EN steel grade S420N material, and there are relatively few cracks and holes. After 25 days, delamination occurs in some parts of carbon steel and weathering steel, and there is no difference in corrosion products, mainly due to the role of alloy elements in the rust layer. The precipitation of Cu and Cr alloy elements in the weathering rust layer can resist the invasion of moisture and harmful ions in the atmosphere, and further corrosion of steel and base metal can be prevented, so as to achieve the effect of atmospheric corrosion resistance.
