Description / Abstract: This specification2 covers steel castings for valves, flanges, fittings, and other pressurecontaining parts intended primarily for lowtemperature service.

Eight grades of ferritic steels and one grade of martensitic steel are covered. Selection of analysis will depend on design and service conditions (Note 1). The temperature shown is the lowest temperature at which the material ordinarily is required to meet the impact requirements of this specification (see Supplementary Requirement S22, Impact Test Temperatures). Users should note that hardenabil. ity of some of the grades mentioned may restrict the maximum size at which the required mechanical properties are obtainable (see Appendix XI).

NoTE 1-This specification covers the low-temperature requirements particularly pertinent for ferritic and martensitic steels. Certain of the grades of austenitic steel castings furnished in accordance with Specification A 351 have been found suitable for lowtemperature service down to -300°F (-l84°C) and others down to —425 0 f (—254 0c) .These grades may be used when impact tested in accordance with this specification A 352 with energy levels and temperatures temperatures of test mutually agreed upon between the purchaser and the manufacturer. As a guide to the selection of energy levels and testing temperatures, Appendix Xl should be consulted.

The values stated in inch-pound units are to be regarded as the standard.
