| A447/A447M | Steel Castings, Chromium-Nickel-Iron Alloy (25-12 Class), for High-Temperature Service |
| A494/A494M | Castings, Nickel and Nickel Alloy |
| A560/A560M | Castings, Chromium-Nickel Alloy |
| A732/A732M | Castings, Investment, Carbon and Low Alloy Steel for General Application, and Cobalt Alloy for High Strength at Elevated Temperatures |
| A743/A743M | Castings, Iron-Chromium, Iron-Chromium-Nickel, Corrosion-Resistant, for General Application |
| A744/A744M | Castings, Iron-Chromium-Nickel, Corrosion Resistant, for Severe Service |
| A747/A747M | Steel Castings, Stainless, Precipitation Hardening |
| A890/A890M | Castings, Iron-Chromium-Nickel-Molybdenum Corrosion-Resistant, Duplex (Austenitic/Ferritic) for General Application |
| A915/A915M | Steel Castings, Carbon and Alloy, Chemical Requirements Similar to Standard Wrought Grades |
| A958 | Steel Castings, Carbon and Alloy, with Tensile Requirements, Chemical Requirements Similar to Standard Wrought Grades |
| A1002 | Castings, Nickel-Aluminum Ordered Alloy |
1.2This specification also covers a group of supplementary requirements that may be applied to the above specifications as indicated therein. These are provided for use when additional testing or inspection is desired and apply only when specified individually by the purchaser in the order.
1.3When investment castings are ordered, the requirements stated in this specification form an integral part of the material specification. In cases of conflict, the requirements of this specification shall take precedence over the individual material specification requirements.
1.4The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
