ASTM A537 Class 2
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.
Masteel UK Limited will supply ASTM A537 Class 2 plates from stock or directly from the mill. We also offer steel cutting services including CAD based flame cutting to cut your steel into particular shapes.
