Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium Corten A sheet inventory 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 Corten A sheet inventory 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.
Large-thickness Corten A sheet inventory, Z35 grade steel plate is a kind of extra-thick steel plate that is applied under specific environmental conditions, such as the key parts such as the turbine seat ring and guide vane of the generator set. It has high requirements for safety, reliability, and long service life. Develop 200mm-300mm thick steel plate of Z35 level, to ensure that the layer tear resistance reaches Z35 level. 300mm thick Z35 grade steel plate can be used not only in the hydropower industry, but also in the manufacture of other large key equipment, and has broad prospects.
After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, Corten A sheet inventory tubes, wires, belts, and profiles have a certain scale, including magnetic, elastic, expanded, bimetal and other precision alloy materials for national defense and electronics industries. In 1982, these plants produced 364,000 tons of Corten A sheet inventory steel and 542,000 tons of steel.
The corten plates Corten A sheet inventory offer high tensile, yield and mechanical strength at the elevated temperature. These plates provide high toughness and harness at the high temperature and cryogenic temperature as well. The application of corrosion Resistant Steel Plates is- these plates are used in the number of industries like landscape building, an automobile company, fertilizers, marine industry. The plate is used in because of its good elasticity, ductility, thermal and electrical conductivity. We follow all the industry-standard both national and international standards.
