Composite steel plate is a composite steel plate which is made of carbon steel or low alloy steel as the base material and coated with stainless steel, titanium alloy, ASTM A709 structural steel and other composite materials, or sandwiched with other metal or non-metal materials between two layers of steel and processed by pressure or blasting. It is mainly used to make chemical equipment and chemical storage tank, or obtain special functions such as shock absorption. The manufacturing methods of composite steel plate include rolling method and explosion method, but most of them are rolling method.ASTM A709 structural steel
The surface hardness of NM400 wear-resistant steel plate usually reaches 360-450HB, and the steel has a high mechanical strength. Its mechanical properties are three to five times that of ordinary low alloy steel plate. NM400 wear-resistant steel plate has excellent mechanical properties and good wear resistance, and can adapt to various mining conditions under different working conditions. NM400 steel can significantly improve the wear resistance of mechanical components, improve the service life of machinery, and reduce production costs.
ASTM A709 structural steel,Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium 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 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.
