A533 Grade B Mn-Mo and Mn-Mo-Ni alloy steel plates

ASTM A533 Grade B in the standard ASTM A533/A533M.ASTM A533 Grade B is a kind of Mn-Mo and Mn-Mo-Ni alloy steel plates material used to fabric high temperature pressure vessels. Just because ASTM A533 Grade B with the special Manganese , Molybdenum , and Manganese, Molybdenum, Nickel chemical composition, ASTM A533 has the right property to be used in high temperature pressure vessel. ASTM A533 Grade B is also a Quenching + Tempering steel material. ASTM A533 have four types A/B/C/D.

Key words:A533 Grade B,ASTM A533 Grade B,A533 Grade B Q&T alloy steel plates,A533 Grade B Mn-Mo and Mn-Mo-Ni alloy steel plates,ASTM A533 Grade B Q&T alloy steel plates for pressure vessels
