ASTM A204 Grade C Pressure Vessel and Boiler Steel Plate

ASTM A204 GR.C is a kind of Mo-alloy steel material used to fabric high temperature pressure vessels. Obviously, A204 this property is based on it is Mo composition. ASTM A-204/A-204M A204 has three grades or levels--Grade A/B/C.

A204 steel grade specification covers molybdenum alloy, intended particularly of welded boilers and others pressure vessels steel plate in A204 Gr. A, A204 Gr .B and A204 Gr .C.
