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.<\/p>\n
1.2 This specification covers powder forged parts made from the following materials:<\/p>\n
1.2.1 CompositionsP\/F-10XX Carbon Steel (produced from atomized iron powder and graphite powder),<\/p>\n
P\/F-10CXX Copper-Carbon Steel (produced from atomized iron powder, copper and graphite powders),<\/p>\n
P\/F-11XX Carbon Steel with manganese sulfide for enhanced machinability (produced from atomized iron powder, manganese sulfide, and graphite powders),<\/p>\n
P\/F-11CXX Copper-Carbon Steel with manganese sulfide for enhanced machinability (produced from atomized iron powder, copper, manganese sulfide, and graphite powders),<\/p>\n
P\/F-42XX Nickel-Molybdenum Steel (produced from prealloyed atomized iron-nickel-molybdenum powder and graphite powder),<\/p>\n
P\/F-46XX Nickel-Molybdenum Steel (produced from prealloyed atomized iron-nickel-molybdenum powder and graphite powder),<\/p>\n
P\/F-44XX Molybdenum Steel (produced from prealloyed atomized iron-molybdenum powder and graphite powder), and<\/p>\n
P\/F-49XX Molybdenum Steel (produced from prealloyed atomized iron-molybdenum powder and graphite powder).<\/p>\n
Note 1 <\/p>\n
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 .<\/p>\n
Note 2 <\/p>\n
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 .<\/p>\n
1.2.2 Grades<\/p>\n
Grade A <\/p>\n
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 .<\/p>\n
Grade B <\/p>\n
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 .<\/p>\n
1.3 Property values stated in inch-pound units are the standard. Conversion factors to SI units may be approximate.<\/p>\n
