ASTM A533 Q&T Mn-Mo and Mn-Mo-Ni alloy steel plates for pressure vessels

ASTM A533 in the standard ASTM A-533/A-533M is a kind of Mn-Mo and Mn-Mo-Ni alloy steel plates material used to fabric high temperature pressure vessels. Just because A533 with the special Manganese , Molybdenum , and Manganese, Molybdenum, Nickel chemical composition, A533 has the right property to be used in high temperature pressure vessel. A533 is also a Quenching + Tempering steel material. A533 have four types A/B/C/D.
