SA204 is a kind of Mo-alloy steel material used to fabric high temperature pressure vessels. Obviously, SA204 this property is based on it's Mo composition. ASME SA204/SA204M SA204 has three grades or levels-- SA204 Grade A, SA204 Grade B, SA204 Grade C
Product: Hot rolled Molybdenum alloy steel plates to be used for pressure vessels
SA204 Grade C steel standard :ASME SA204/SA204M
SA204 Grade C applicable thickness: Max 100mm
