ASTM A204 Grade A is a kind of Mo-alloy steel material used to fabric high temperature pressure vessels.
A204 this property is based on it's 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 Grade A, A204 Grade B and A204 Grade C.
