Withdrawn Standard: Standard Specification for Steel, Closed-Impression Die Forgings for General Industrial Use (Withdrawn 2018)
ASTM A521/A521M
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 CAāUntreated, carbon steel forgings,
1.2.2 Grades CC, CC1, and CEāAnnealed, normalized and tempered, carbon steel forgings,
1.2.3 Grade CFāNormalized and tempered carbon steel forgings,
1.2.4 Grade CF1āDouble normalized and tempered carbon steel forgings,
1.2.5 Grade CGāQuenched and tempered, or normalized, quenched and tempered carbon steel forgings,
1.2.6 Grade AAāAnnealed, normalized, or normalized and tempered alloy steel forgings,
1.2.7 Grades AB and ACāNormalized and tempered alloy steel forgings, and
1.2.8 Grades AD, AE, AF, AG, and AHāNormalized, quenched, and tempered alloy steel forgings.
1.3 Unless the order specifies the applicable āMā 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.
