Pressure vessel steel plate ASTM A516 grade 70 is primarily intended for use in welded pressure vessels where notch toughness is important. The pressure vessel steel plate ASTM A516 grade 70 thinner than 40mm is normally supply as rolled. And pressure vessel steel plates ASTM A516 grade 70 above 40mm thick are supplied in normalized. The application of A516 grade 70 steel is up to pressure vessel steel plate ASTM A516 grade 70 properties to a large extent.
