AASHTO M 102M/M 102 2006 Edition, January 1, 2006 Standard Specification for Steel Forgings, Carbon and Alloy, for General Industrial Use
More info
Description / Abstract:
This specification covers untreated and heat-treated carbon and alloy steel forgings for general industrial use. ASTM specifications for forgings are available for specific applications such as pressure vessels, railroad use, turbine generators, gearing, and others involving special temperature requirements.
Hot-rolled or cold-finished bars are not within the scope of this specification.
Six classes of carbon steel and seven classes of alloy steel forgings are listed (Section 7), which indicates their required heat treatments as well as mechanical properties.
Provision, with the suffix “H” for certification and marking, for the supply of forgings after hardness testing only.
Supplementary requirements, including those in ASTM A788, of an optional nature, are provided. These shall apply only when specified by the purchaser.
Appendix X1 lists the current classes corresponding to the various classes of ASTM A235, A237, and A243, which have been superseded by this specification.
The values stated in either SI units or inch-pound units are to be regarded separately as the standard; within the text and tables, the inch-pound units are shown in brackets. The values stated in each system are not exactly equivalent; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
