1.1 This specification covers powder forged ferrous materials fabricated by hot densification of atomized prealloyed or iron powders and intended for use as structural parts. 1.2 This specification covers powder forged parts made from the following materials: 1.2.1 Compositions: 1.2.1.1 PF-10XX Carbon Steel (produced from atomized iron powder and graphite powder), 1.2.1.2 PF-10CXX Copper-Carbon Steel (produced from atomized iron powder, copper and graphite powders), 1.2.1.3 PF-11XX Carbon Steel with manganese sulfide for enhanced machinability (produced from atomized iron powder, manganese sulfide, and graphite powders), 1.2.1.4 PF-11CXX, PF-1130CXX, and PF-1135CXX Copper-Carbon Steels with manganese sulfide for enhanced machinability (produced from atomized iron powder, copper, manganese sulfide, and graphite powders), 1.2.1.5 PF-42XX Nickel-Molybdenum Steel (produced from prealloyed atomized iron-nickel-molybdenum powder and graphite powder), 1.2.1.6 PF-46XX Nickel-Molybdenum Steel (produced from prealloyed atomized iron-nickel-molybdenum powder and graphite powder), 1.2.1.7 PF-44XX Molybdenum Steel (produced from prealloyed atomized iron-molybdenum powder and graphite powder), and 1.2.1.8 PF-49XX Molybdenum Steel (produced from prealloyed atomized iron-molybdenum powder and graphite powder). Note 1: Alloy composition designations are modifications of
the AISI-SAE nomenclature. For example: 10CXX designates a plain
carbon steel containing copper and XX amount of carbon.
Compositional limits of alloy and impurity elements may be
different from the AISI-SAE limits. Chemical composition limits are
specified in Section 6.
Note 2: XX designates the forged carbon content, in hundredths
of a percent, that is specified by the purchaser for the
application. For a given specified carbon content, the permissible
limits shall be as specified in 6.2.
Note 3: The old acronym for powder forging P/F has been
replaced by PF throughout the document. The change in the prefix
for the material designations is just to match the currently
approved acronym for powder forging. No change has been made to the
material specification and performance characteristics for the
various powder forged materials.
1.2.2 Grades: 1.2.2.1 Grade A—Density equivalent to a maximum of 0.5 % porosity. The minimum density of those sections of the powder forged part so designated by the applicable part drawing shall not be less than the value specified in Table 1. 1.2.2.2 Grade B—Density equivalent to a maximum
of 1.5 % porosity. The minimum density of those sections of the
powder forged part so designated by the applicable part drawing
shall not be less than the value specified in Table 1.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. |
