Description / Abstract:

This specification covers iron-chromium. iron-chromium-nickel, nickel-molybdenum. nickel, and nickel-copper alloy castings for corrosion-resistant service. The grades covered by this specification represent types of alloy castings suitable for broad ranges of application which are intended for a wide variety of corrosion-resistant applications.

NOTE 1—For general heat-resistant alloy castings. reference should be made to ASTM Specification A 297, for Heat-Resistant Iron-Chromium and Iron-Chromium-Nickel Alloy Castings for General Application.2

NOTE 2—required unless it is specified in the purchase order. I f so specified. the test shall be performed by the manufacturer in accordance with the appropriate ASTM recommended practice for the particular grade involved. as listed in ASTM Recommended Practices A 262, for Detecting Susceptibility to Intergranular Attack in Stainless Steels, 3 or as agreed upon with the purchaser. Intergranular corrosion tests on stabilized or 0.03 percent carbon maximum grades (CF-3. CF-3M and CF-8C) shall be made on sensitized specimens. On all other grades of chromium-nickel steels, intergranular corrosion tests shall be made on specimens representative of the as-shipped condition. In cutting a sample of the material to convenient testing size, bear in mind that the specimen should represent as nearly as practical the surface of the material as it will be used in service. Only such surface finishing should be performed as is necessary to remove foreign material and obtain a uniform standard finish as called for in the appropriate Recommended Practice A 262.

NOTE 3—The values stated in U.S. customary units are to be regarded as the standard.
