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

Grade CA - Untreated, carbon steel forgings,

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

Grade CF - Normalized and tempered carbon steel forgings,

Grade CF1 - Double normalized and tempered carbon steel forgings,

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

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

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

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

The values stated in inch-pound units are to be regarded as the standard.
