3.Application:

ASTM A537 CL2 steel plates are engineered to be used in pressure vessel applications.ASTM A537 CL2 steel is a higher yield and tensile strength material used in the fabrication of pressurised vessels and steel boilers. ASTM A537 CL2 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 CL2 is a material used extensively by the oil, gas and petrochemical industry.
