Scope of standard 1.1 This specification covers a group of requirements that are mandatory requirements of the following steel casting specifications issued by ASTM. If the product specification specifies different requirements, the product specification shall prevail.ASTM Designation Title of SpecificationA 27/A 27MSteel Castings, Carbon, for General ApplicationA 128/A 128MSteel Castings, Austenitic ManganeseA 148/A 148MSteel Castings, High Strength, for Structural PurposesA 297/A 297M Steel Castings, Iron-Chromium and Iron-Chromium-Nickel, Heat Resistant for General ApplicationA 447/A 447MSteel Castings, Chromium-Nickel-Iron Alloy (25-12 Class), for High-Temperature ServiceA 494/A 494MCastings, Nickel and Nickel AlloyA 560/A 560MCastings, Chromium-Nickel AlloyA 743/A 743MCastings, Iron-Chromium, Iron-Chromium-Nickel, Corrosion Resistant, for General ApplicationA 744/A 744MCastings, Iron-Chromium-Nickel, Corrosion Resistant, for SevereA 747/A 747M Steel Castings, Stainless, Precipitation HardeningA 890/A 890MCastings, Iron-Chromium-Nickel-Molybdenum Corrosion-Resistant, Duplex (Austenitic/Ferritic) for General ApplicationA 915/A 915MSteel Castings, Carbon and Alloy, Chemical Requirements Similar to Standard Wrought GradesA 958Steel Castings, Carbon and Alloy, with Tensile Requirements, Chemical Requirements Similiar to Standard Wrought GradesA 1002Castings, Nickel-Aluminum Ordered Alloy1.2 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 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.
