Standard Specification for Corrosion-Resistant Iron-Chromium, Iron-Chromium-Nickel, and Nickel Base Alloy Castings for General Application
|Publication Date:||15 August 1968|
This specification covers iron-chromium, iron-chromium-nickel
NOTE 1.-For general heat-resistant alloy castings, reference
should be made to the Specifications for Heat-Resistant
Iron-Chromium and Iron-Chromium-Nickel
NOTE 2.-The intergranular corrosion test is not required unless it is specified in the purchase order. If 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 the Recommended Practices A 262, for Detecting Susceptibility to Intergranular Attack in Stainless Steels3, or as agreed upon with the purchaser. Intergranular corrosion tests on stabilized or 0.03 per cent 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 asshipped 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.
