    1、Designation: A 1002 99 (Reapproved 2003)Standard Specification forCastings, Nickel-Aluminum Ordered Alloy1This standard is issued under the fixed designation A 1002; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last

    2、revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers nickel-aluminum ordered alloycastings intended for heat-resisting and elevated-temperatureapplic

    3、ations such as heat-resistant alloy structural members,containers, supports, hangers, spacers, and so forth, in envi-ronments up to 2300F (1260C).1.2 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard. Within the text, theSI units are shown in brackets.

    4、 The values stated in eachsystem are not exact equivalents; therefore, each system mustbe used independently of the other. Combining values from thetwo systems may result in nonconformance with this specifi-cation.2. Referenced Documents2.1 ASTM Standards:A 370 Test Methods and Definitions for Mecha
