    1. Scope

    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 Specification
    A27/A27M Steel Castings, Carbon, for General Application
    A128/A128MSteel Castings, Austenitic Manganese
    A148/A148MSteel Castings, High-Strength, for Structural Purposes
    A297/A297M Steel Castings, Iron Chromium and Iron-Chromium-Nickel, Heat Resistant for General Application
    A447/A447M Steel Castings, Chromium-Nickel-Iron Alloy (25-12 Class), for High-Temperature Service
    A486/A486MSteel Castings, for Highway Bridges
    A494/A494MCastings, Nickel and Nickel Alloy
    A560/A560MCastings, Chromium-Nickel Alloy
    A743/A743MCastings, 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/A915MSteel Castings, Carbon and Alloy Chemical

    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 A781 and SI units for material ordered to Specification A781M.
