ASTM A204 Grade B steel (also called ASME SA204 Grade B plate) is a kind of molybdenum-alloy steel plates, which is particularly for welded boilers and high temperature pressure vessels. ASTM A204 steel plate covers 3 grades: A204 Grade A, A204 Grade B, A204 Grade C. The maximum plate thickness is limited only by the chemical composition to achieve certain mechanical property figure; steel plate and coils under this specification normally limit thickness as follows: ASTM A204 grade A: 6 in[150mm]; ASTM A204 grade B: 6 in[150mm]; ASTM A204 grade C: 4 in[100mm].
