1.1This specification2 covers high-strength quenched and tempered low-alloy steel forged parts for pressure vessels. The maximum thickness of forgings under this specification shall be 1¹/₂in. [38 mm] for Grade A, and 4 in. [100 mm] for Grades E and F.

1.2Although no provision is made for supplementary requirements in this standard, the supplementary requirements in Specification A788/A788M may be considered by the purchaser.

1.3Welding technique is of fundamental importance and it is presupposed that welding procedures will be in accordance with approved methods for the class of material used.

1.4The values stated in either SI units or inch-pound units are to be regarded separately as standard.
