ASTM A521-96-Reapproved2001<\/h3>\n

Historical Standard: Standard Specification for Steel, Closed-Impression Die Forgings for General Industrial Use<\/h4>\n
\n

ASTM A521<\/h4>\n

Scope<\/strong><\/p>\n

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

Note 1\u2014For the definition of a forging, refer to Definition A 509.<\/p>\n

1.2 The classes of forgings are as follows, the choice depending on design and stress or service to be imposed:<\/p>\n

1.2.1 Class CA<\/i>\u2014Untreated, carbon steel forgings,<\/p>\n

1.2.2 Classes CC, CC1 and CE<\/i>\u2014 Annealed, normalized and tempered, carbon steel forgings,<\/p>\n

1.2.3 Class CF<\/i>\u2014Normalized and tempered carbon steel forgings,<\/p>\n

1.2.4 Class CF1<\/i>\u2014 Double normalized and tempered carbon steel forgings,<\/p>\n

1.2.5 Class CG<\/i>\u2014Quenched and tempered, or normalized, quenched and tempered carbon steel forgings,<\/p>\n

1.2.6 Class AA<\/i>\u2014Annealed, normalized, or normalized and tempered alloy steel forgings,<\/p>\n

1.2.7 Classes AB and AC<\/i>\u2014Normalized and tempered alloy steel forgings, and<\/p>\n

1.2.8 Classes AD, AE, AF, AG and AH<\/i>\u2014Normalized, quenched, and tempered alloy steel forgings.<\/p>\n

Note 2\u2014The appendix tables list recommended tolerances for a number of materials other than those covered by the above classes. The tables are for information only and the purchaser must define the condition in which he desires forgings made from materials not described above.<\/p>\n

1.3 The values stated in inch-pound units are to be regarded as the standard.<\/p>\n
