|Publication Date:||24 June 1977|
|ICS Code (Iron and steel forgings):||77.140.85|
This specification covers untreated and heat-treated carbon and alloy steel forgings for general industrial use. Other ASTM specifications for forgings are available for specific applications such as pressure vessels, railroad use, turbine generators, gearing, and others involving special temperature requirements.
Six classes of carbon steel and seven classes of alloy steel forgings are listed in Table 3, which indicates their required heat treatments, as well as mechanical properties.
Supplementary requirements of an optional nature are provided. These shall apply only when specified by the purchaser.
The appendix lists the grades corresponding to the various grades of the superseded ASTM Specifications A 235, A 237, and A 243.
Note-The values stated in U.S. customary units are to be regarded as the standard.
