ASTM B783-99e1 - 14.3.2000
 
1. Scope

1.1 This specification covers a variety of ferrous P/M structural materials and includes a classification system or material designation code. With the classification system, this specification includes chemical composition, minimum tensile yield strength for parts in the as-sintered condition, and minimum ultimate tensile strength for materials in the heat-treated condition.

1.2 Property values stated in inch-pound units are the standard. Conversion factors to SI units may be approximate.

Note 1-Paragraphs 5.1 and 7.1 will govern material classification by the designation code. The classification system is explained in Appendix X1.
