ASTM A302 GR.B Mn-Mo Alloy Pressure Vessel Steel Plate Descriptions:

ASTM A302 standard specification for pressure vessel plates in alloy steel, manganese molybdenum and manganese-molybdenum-nickel.
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.
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.
Supplementary Technology: HIC Test | NACE MR0175 | Z15 | Z25 | Z35 |

Thickness: 6MM to 300MM,
Width: 1500mm to 4050mm,
Length: 3000mm to 15000mm
