1.1 This specification covers high-strength low-alloy steel plates for service in welded pressure vessels and piping components.

1.2 This material is particularly intended for piping and pressure vessel applications where high strength and improved toughness are required.

1.3 Two grades, designated B and C, are covered by this specification. Grade B provides a minimum yield strength of 50 ksi [345 MPa]. Grade C provides a minimum yield strength of 60 ksi [415 MPa].

1.4 The maximum thickness of plates is limited only by the capacity of the chemical composition and heat treatment to meet the specified mechanical property requirements. Individual manufacturers should be consulted on thickness limitations since current industry limitations have not been ascertained to date.

1.5 The values stated in either inch-pound units or SI units are to be regarded separately as 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 noncomformance with the specification.


This specification covers high-strength low-alloy steel plates for service in welded pressure vessels and piping components. This material is particularly intended for piping and pressure vessel applications where high strength and improved toughness are required. Two grades, designated B and C, are covered. The steel shall be killed and shall conform to the fine austenitic grain size requirements specified. The material shall be normalized by heating to a suitable temperature which produces an austenitic structure holding a sufficient time to attain uniform heat throughout the material, and cooling in air. The steel shall conform to the requirements as to chemical compositions specified. The material as represented by the tension test specimen shall conform to the requirements specified.
