The wear-resistant plate has high wear resistance and good impact properties. It can be laser cut, bent, welded, etc., and can be connected with other structures by welding, plug welding, screw connection and other methods. The whole process of inspection and repair It has the characteristics of time-saving and convenient. Products P355GH material are widely used in manufacturing industries such as metallurgical industry, coal, concrete, power engineering, laminated glass, mining, decorative building materials, brick kilns, etc.

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 p355gh material alloy steel p355gh material 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.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium p355gh material carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some p355gh material alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.
