In recent years, in line with the development trend of iron and S420NL 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 S420NL 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.
S420NL steel plate, Manganese steel plate is a low alloy high strength steel plate with good weldability. Manganese steel plate is the main material of general pressure vessel. Manganese steel plate is mainly used to make engineering structural parts, roof beam of workshop and tower crane tower body. Manganese steel plate has high rupture strength and creep strength at high temperature and good impact toughness at low temperature. High strength steel is a kind of wear-resistant steel for heavy industry. Its application fields include quarrying, mining, mining, coal industry, casting and steel industry, etc.
Bridge steel S420NL steel plate is required to have higher strength, toughness, load and impact of rolling stock, and good fatigue resistance, low temperature toughness and atmospheric corrosion resistance. With the development of domestic railway construction towards high speed and heavy load, railway bridge steel developing in the direction of high speed, heavy load, long span, beautiful and novel structure, and full welding, higher requirements are imposed on the properties of steel for bridges. In particular, the development of cross-sea bridges has put forward higher requirements on the corrosion resistance of steel for bridges.
Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched S420NL steel plate increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of S420NL steel plate during tempering, while tempering determines the performance and life of the workpiece.
