Abstract

This specification covers a variety of ferrous powder metallurgy structural materials and includes a classification system or material designation code. The classification system includes chemical composition, minimum offset yield strength for as-sintered materials, minimum ultimate tensile strength for heat-treated materials (sinter hardened or quenched and tempered), minimum density, and maximum coercive field strength requirements for iron-phosphorus materials. Structural parts shall be made by pressing and sintering metal powders with or without subsequent heat treatment. Parts may also be made by repressing or repressing and resintering sintered parts, if necessary, with or without subsequent heat treatment to produce finished parts conforming to the requirements of this specification. The material shall conform to the chemical composition requirements for iron, copper, carbon, nickel, molybdenum, chromium, manganese, silicon, sulfur, phosphorus, nitrogen, columbium, and oxygen. The material shall be subjected to chemical analysis and mechanical tests.

Scope

1.1 This specification covers a variety of ferrous P/M structural materials and includes a classification system or material designation code. The classification system used in this specification includes chemical composition, minimum tensile; 0.2 % offset yield strength for as-sintered materials and minimum ultimate tensile strength for heat-treated materials (sinter hardened or quenched and tempered). It also contains minimum density and maximum coercive field strength requirements for iron-phosphorus materials. Material classification is governed by the designation code which is explained in Appendix X1. The data provided display typical mechanical properties achieved under commercial manufacturing procedures. Physical and mechanical property performance characteristics can change as a result of subsequent processing steps beyond those designated in this standard. These changes could improve or degrade the properties.

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