The A537 / SA537 standard, its full name is “Standard Specification for Pressure Vessel Plates, Heat-Treated, Carbon-Manganese-Silicon Steel”, is intended use in the manufacture of fusion welded pressure vessels and structures.
ASTM A537 Class 2 steel is a higher yield and tensile strength material used in the fabrication of pressurised vessels and steel boilers.
The steel includes the alloying of carbon, manganese and silicon and is heat treated using the quenched and tempered method which gives the material its residual strength. Sourced by the world's leading fabricators, ASTM A537 Class 2 is a material used extensively by the oil, gas and petrochemical industry.
