ASTM A516 gr70 steel plates are mainly used in welded pressure vessels where improved notch toughness is important. Generally As Rolled is ok for rolling ASTM A516 gr70 steel plate. However, in order to improve ASTM A516 gr70 steel property and toughness, it is suggested to do normalizing for ASTM A516 gr70 steel plates especially for the plates above 40mm thick. NACE MR-0175 ASTM A516 gr70 steel plate is also offered by BBN steel with HIC test and SSCC test.
