ASME SA542 Grade B Class 2 Alloy Steel Plate for Pressure Vessel, SA542GrBCL2 Steel Plate Fixed-rolled
ASME SA542 Grade B Class 2 is an alloy steel plate for pressure vessels
SA542 SA-542/SA-542M standard class B class 2 is a kind of molybdenum-vanadium alloy steel plate material for high-temperature pressure vessels. There are five grades or levels of SA542. They are: A, B, C, D, E. SA542 Grade B Class 2 requires (quenching + tempering) heat treatment to meet the performance requirements in standard ASTM SA-542/SA-542M.
