SB450M STEEL PLATE

JIS G3103 SB450M,SB450M steel plate,SB450M steel sheet contains Mo alloy in chemical composition comparing with boiler steel plate SB450.Normally as rolled or hot rolled is ok for pressure vessel steel plate SB450M,of course,Normalized delivery condition would be better way for these boiler steel plates SB450M.Ultrasonic test shall be done for boiler steel plate SB450M,our engineers suggest doing UT standard under ASTM A435/A435M or A577/A577M or A578/A578M which including level A,level B and level C.A578-C is the best level.The best similar steel grade is ASTM A204GrA to SB450M.
