A302 Grade C steel plates standard specification for pressure vessel plates in alloy steel, manganese molybdenum and manganese-molybdenum-nickel. A302 Grade C steel plate shall be normally supplied in the as-rolled condition. Plates may be ordered normalized or stress relieved, or both. If A302 Grade C above 50mm in thickness shall be normalized.
ASTM A302 Grade C Pressure Vessel And Boiler Steel Plate are used in Pressure Vessel,Boiler,Storage Tanks and Heat Exchanger in Oil,Gas Project.
