JIS G3103 SB480 Room and cold temperatures Pressure Vessel Steel plate

Mo alloy boiler steel plate SB480M is mainly used for building pressure vessels.The minimum yield strength of SB480M shall be above 275Mpa,and tensile strength of SB480M shall be within 480-620Mpa.For boiler steel plate SB480M with thickness exceeding 38mm shall be normalized when rolling,and belows or equal to 38mm thickness,as rolled is ok.Besides,Ultrasonic test is necessary,and high tension,simulated post welded heat treatment shall be chosed by the end users,such as boiler manufacturers,heat exchanger plants.The best similar steel grade is ASTM A204GrB to SB480M

STEEL DIMENSION:
Thickness: 6MM to 300MM,
Width: 1500mm to 4050mm,
