Under
ASTM A302/A302M steel specification,there are four steel grades,such as A302 Grade A boiler steel plate,A302 Grade B pressure vessel steel plate,A302 Grade C boiler steel plate and A302 Grade D pressure vessel steel plate.Pressure vessel steel plate SA302 Grade A is manganese-molybdenum alloy steel plates intended particularly for welded boilers and other pressure vessels.Boiler steel plate A302 Grade A shall be with minimum yield strength at 310Mpa,and tensile strength within 515-655 Mpa.
Application: ASTM A302 Grade A(A302GRA) Pressure Vessel And Boiler Steel Plate are used in Pressure Vessel,Boiler,Storage Tanks and Heat Exchanger in Oil,Gas Project.
A302 Grade A boiler steel plate 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.
