    ASTM A351 / A351M

    1. Scope

    1.1 This specification covers austenitic steel castings for valves, flanges, fittings, and other pressure-containing parts (Note 0). Note 0Carbon steel castings for pressure-containing parts are covered by Specification A 216/A 216M, low-alloy steel castings by Specification A 217/A 217M, and duplex stainless steel castings by Specification A 995/A 995M.

    1.2 A number of grades of austenitic steel castings are included in this specification. Since these grades possess varying degrees of suitability for service at high temperatures or in corrosive environments, it is the responsibility of the purchaser to determine which grade shall be furnished. Selection will depend on design and service conditions, mechanical properties, and high-temperature or corrosion-resistant characteristics, or both.

    1.2.1 Because of thermal instability, Grades CE20N, CF3A, CF3MA, and CF8A are not recommended for service at temperatures above 800F [425C].

    1.2.2 Because of embrittlement phases, Grade CD4MCu is not recommended for service at temperatures above 600F [316C].

    1.3 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 nonconformance with the specification.
