Standard Specification for Structural Steel for Ships
1.1This specification covers structural steel plates, shapes, bars, and rivets intended primarily for use in ship construction.
1.2Material under this specification is available in the following categories:
1.2.1Ordinary Strength-Grades A, B, D, and E with a specified minimum yield point of 34 ksi [235 MPa], and
1.2.2Higher Strength-Grades AH, DH, EH, and FH with a specified minimum yield point of 46 ksi [315 MPa], 51 ksi [350 MPa], or 57 ksi [390 MPa].
1.3Shapes and bars are normally available as Grades A, AH32, and AH36. Other grades may be furnished by agreement between the purchaser and the manufacturer.
1.4The maximum thickness of products furnished under this specification is 4 in. [100 mm] for plates and 2 in. [50 mm] for shapes and bars.
1.5When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X3 of Specification A6/A6M for information on weldability.
1.6The values stated in either inch-pound units or SI units are to be regarded separately as the standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.
