Organization: ASTM International
Publication Date: 1 April 2011
Status: inactive
Page Count: 9
ICS Code (Iron and steel forgings): 77.140.85
scope:

1.1 This specification covers untreated and heat-treated steel, closed-impression die forgings (Note 1) for general industrial use.

Note 1-For the definition of a forging, refer General Requirements Specification A788/A788M.

1.2 The Grades of forgings are as follows, the choice depending on design and stress or service to be imposed:

1.2.1 Grade CA-Untreated, carbon steel forgings,

1.2.2 Grades CC, CC1, and CE-Annealed, normalized and tempered, carbon steel forgings,

1.2.3 Grade CF-Normalized and tempered carbon steel forgings,

1.2.4 Grade CF1-Double normalized and tempered carbon steel forgings,

1.2.5 Grade CG-Quenched and tempered, or normalized, quenched and tempered carbon steel forgings,

1.2.6 Grade AA-Annealed, normalized, or normalized and tempered alloy steel forgings,

1.2.7 Grades AB and AC-Normalized and tempered alloy steel forgings, and

1.2.8 Grades AD, AE, AF, AG, and AH-Normalized, quenched, and tempered alloy steel forgings.

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

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