A573Gr70 Steel Plate For Pressure Vessel
A573Gr70 is a kind of high strength pressure vessel steel plate, which is widely used in petroleum, chemical industry, energy and other fields. Due to its excellent mechanical properties and corrosion resistance, the A573Gr70 has significant advantages in the manufacture of high-pressure vessels, reactors, storage tanks, etc.
A573Gr70 steel sheet is usually delivered in annealed condition. Annealing treatment can improve the softness and ductility of the steel plate, which is convenient for processing and forming. In specific cases, in order to meet customer requirements for special properties, other heat treatment processes can also be carried out, such as quenching and tempering.
