    ASTM A289 / A289M

    1. Scope

    1.1 This specification covers nonmagnetic alloy steel retaining ring forgings for generators.

    1.2 The values stated in either inch-pound units or SI (metric) units are to be regarded separately as standards. Within the text and tables, the SI units are shown in brackets. the values in each system are not exact equivalents; therefore each system must be used independent of the other. Combining values from the two systems may result in nonconformance with the specification.

    1.3 Unless the order specifies the applicable "M" specification designation, the material shall be furnished to the inch-pound units.
