About ASTM A302
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. 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. It is manufactured for Pressure Vessel, Boiler, Storage Tanks and Heat Exchanger in Oil, Gas Project.
We can offer ASTM A302/A302M A302 Grade B,A302 Gr.B Boiler and Pressure vessel steel
Pressure vessel steel plate ASTM A302/A302M A302 Grade B under steel standard ASME SA302/SA302M which is manganese-molybdenum alloy steel plates intended particularly for welded boilers and other pressure vessels.
According to their strength levels,there are different grades A302 Grade A,A302 Grade B,A302 Grade C and A302 Grade D.Pressure vessel steel plate A302 Grade A owned tensile strength within 515-655 Mpa,minimum yield strength is 310 Mpa,and pressure vessel steel plate A302 Grade B owned tensile strength at 550-690 Mpa.
