In recent years, in line with the development trend of iron and A709 Gr HPS70W bridge steel plate steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which A709 Gr HPS70W bridge steel plate are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
NM400 steel is a high-strength wear-resistant steel plate. A709 Gr HPS70W bridge steel plate, NM400 steel has quite high mechanical strength; its mechanical properties are 3 to 5 times that of ordinary low alloy steel plates; NM400 steel plate can significantly improve the wear resistance of mechanical related parts; therefore, it can increase the service life of machinery and reduce production costs. NM400 wear-resistant steel plate is mainly used for processing and manufacturing of wear-resistant and wearing parts for mining and various construction machinery.
Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This A709 Gr HPS70W bridge steel plate alloy steel A709 Gr HPS70W bridge steel plate still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.
The effect of alloy elements of A709 Gr HPS70W bridge steel plate, Q345B alloy steel plate on tempering transformation: improving the tempering stability. The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process. Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved.
