Specification :
SA542 in the standard SA-542/SA-542M is a kind of Mo-V alloy steel plates material used to fabric high temperature pressure vessels. SA542 have Five grades or levels. They are : grade A, grade B, grade C, grade D, grade E . SA542 need to be done the (Quenching + Tempering ) heat-treatment to meet the property requirement in the standard ASTM SA-542/SA-542M.
