3、t of Defense.1. Scope*1.1 This specification2covers carbon steel plates of low- and intermediate-tensile strengths which may be made by killed,semi-killed, capped, or rimmed steel practices at the producers option. These plates are intended for fusion-welded pressurevessels.1.2 Plates under this spe

4、cification are available in three grades having different strength levels as follows:Grade Tensile Strength, ksi MPaA 4565 310450B 5070 345485C 5575 3805151.3 The maximum thickness of plates under this specification, for reasons of internal soundness, is limited to a maximumthickness of 2 in. 50 mm
