|A 128/A 128M||Steel Castings, Austenitic Manganese|
|A 148/A 148M||Steel Castings, High-Strength, for Structural Purposes|
|A 297/A 297M||Steel Castings, Iron Chromium and Iron-Chromium-Nickel|
|A 447/A 447M||Steel Castings, Chromium-Nickel-Iron|
|A 486/A 486M||Steel Castings, for Highway Bridges|
|A 494/A 494M||Castings, Nickel and Nickel Alloy|
|A 560/A 560M||Castings, Chromium-Nickel Alloy|
|A 743/A 743M||Castings, Iron-Chromium, Iron-Chromium-Nickel|
|A 744/A 744M||Castings, Iron-Chromium-Nickel|
|A 747/A 747M||Steel Castings, Stainless, Precipitation Hardening|
|A 890/A 890M||Castings, Iron-Chromium-Nickel|
|A 915/A 915M||Steel Castings, Carbon and Alloy, Chemical Requirements Similar to Standard Wrought Grades|
|A 958||Steel Castings, Carbon and Alloy, with Tensile Requirements, Chemical Requirements Similiar to Standard Wrought Grades|

1.2 This 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.
1.3 The requirements of the individual material specification, and this general specification shall prevail in the sequence named.
1.4 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. Inch-pound units are applicable for material ordered to Specification A 781 and SI units for material ordered to Specification A 781M.
