- Commodity name: A302 GR.B Alloy Pressure Vessel Steel Plate
A302 Grade B steel plates standard specification for pressure vessel plates in alloy steel, manganese molybdenum and manganese-molybdenum-nickel. A302 Grade B steel plate shall be normally supplied in the as-rolled condition. Plates may be ordered normalized or stress relieved, or both. If A 302 Grade B above 50mm in thickness shall be normalized.
A302 GR.B Alloy Pressure Vessel Steel Plate Descriptions:
This specification covers manganese-molybdenum and manganese-molybdenum-nickel alloy steel plates intended particularly for welded boilers and other pressure vessels. ASTM A302 is a kind of low alloy steel specification covers 4 different grades(A, B, C, D), Grade C and D contains chemical composition Ni, with the same thickness, yield and tensile strength of Grade C is the same of Grade B, while elongation rate of grade C is higher.This specification covers manganese-molybdenum and manganese-molybdenum-nickel alloy steel plates intended particularly for welded boilers and other pressure vessels.
