SA225 is a kind of Mn-V-Ni alloy steel material used to fabric high temperature pressure vessels. Obviously, SA225 this property is based on it's Mn, V, Ni composition. ASME SA225/SA225M A225 has two grades or levels-- SA225 Grade C, SA225 Grade D
Product: Hot rolled Manganese-Vanadium-nickel alloy steel plates intended primarily for welded layered pressure vessels.
SA225 Grade D steel standard :ASME SA225/SA225M
SA225 Grade D applicable thickness: Max 150mm
SA225 Grade D delivery condition: AR(As rolled), N(Normalized)
