\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 General Requirements Specification A 788.<\/p>\n

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

1.2.1 Grade CAUntreated, carbon steel forgings,<\/p>\n

1.2.2 Grades CC, CC1, and CEAnnealed, normalized and tempered, carbon steel forgings,<\/p>\n

1.2.3 Grade CFNormalized and tempered carbon steel forgings,<\/p>\n

1.2.4 Grade CF1Double normalized and tempered carbon steel forgings,<\/p>\n

1.2.5 Grade CGQuenched and tempered, or normalized, quenched and tempered carbon steel forgings,<\/p>\n

1.2.6 Grade AAAnnealed, normalized, or normalized and tempered alloy steel forgings,<\/p>\n

1.2.7 Grades AB and AC Normalized and tempered alloy steel forgings, and<\/p>\n

1.2.8 Grades AD, AE, AF, AG, and AHNormalized, quenched, and tempered alloy steel forgings.<\/p>\n

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