Product Scope：

ANSON STEEL produces ASTM A537 of all grades, ASTM A537 specification covers the standard for heat-treated carbon manganese-silicon steel plates intended for fusion welded pressure vessels and storage tank. It is a kind of low alloy steel that covers 3 grades (Class 1, Class 2, Class 3) , steel plate of these grades are used when yield and tensile strength of ASTM A516 can not meet the requirements of pressure services like boiler and pressure vessels in oil, gas, petroleum industries.

ASTM A537 class1 steel plate typical applications are API 650 and API 620 storage tanks, pressure vessels designed for moderate and lower-temperature service, requiring excellent notch toughness. Class 1 steel is finished as Normalized and Class 2 is finished as Quenched & Tempered plates. A537 Class 1 steel plate shows good cold forming performance, for welding, special consumables and welding methods are needed for avoiding harmful effects of metal structure.
