The toughness of steel such as NM400 material steel is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.
The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, NM400 material steel seamless steel pipes for ships and petroleum cracking NM400 material steel steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many NM400 material steel products have been exported to the Middle East, India, Southeast Asia and Europe and America.
abrasion resistant steel plate has high wear resistance and good impact performance. NM400 material steel, Abrasion resistant steel plate can be cut, bent and welded. Abrasion resistant steel plate can be connected with other structures by welding, plug welding and bolt connection. It is time-saving and convenient in the maintenance process. Abrasion resistant steel plate is widely used in metallurgy, coal, cement, power, glass, mining, building materials, brick and tile industries. NM400 material steel, Abrasion resistant steel plate has a very high cost performance, and has been favored by more and more industries and users.
