ASME SA537 covers heat treated carbon steel sheets for pressure vessel applications. SA537 steel plate contains chemical elements such as carbon, manganese and silicon. Under ASME standard, SA537 class 1 is supplied under standard conditions and SA537 class 2 is supplied after quenching and tempering. ASME SA537 steel sheet has greater tensile strength and yield strength, and it can be used for petrochemical industry pressure vessel and boiler manufacturing.
