SA542 have five grades or levels. They are : grade A, grade B, grade C, grade D, Grade E.SA542 Grade A need to be done the (Quenching + Tempering ) heat-treatment to meet the property requirement in the standard ASME SA-542/SA-542M.
ASME SA542 Grade A in the standard SA-542/SA-542M is a kind of Mo-V alloy steel plates material used to fabric high temperature pressure vessels.
Standard : ASME SA-542/SA-542M
Dimension range :3mm -260mm x 1000mm-4000mm x 1000mm-18000mm

① In SA 542/SA 542M-82 standard and the earlier standard, the steel plates whose thickness ≤ 125mm, C must be ≤ 0.15%
② Ca can be replace by REM as the agreement with manufacturer and buyer, if like this, then the total amount of REM should be stated.
Delivery Status : Quenching + tempering
ASME SA542 Grade A Ni alloy steel plate/sheet application :
SA542 Grade A steel plate is mainly used in petroleum, chemical industry, power station, boiler and other industries, for the production reactor, heat exchanger, separator, spherical tank, oil tank, liquefied gas tank, nuclear reactor pressure shell, boiler drum, liquefaction Oil cylinders, high-pressure water pipe hydropower station, turbine volute and other equipment and components.
