The strcutural parts shall be made by hot forging of powder metallurgy preforms in confined dies with or without subsequent heat treatment. The materials shall conform to the required chemical composition for nickel, molybdenum, manganese, copper, chromium, sulfur, silicon, phosphorus, carbon, and oxygen. The mechanical properties such as yield strength, elongation, Rockwell hardness, impact energy, compressive yield strength and fatigue shal be determined using the tensile test method, Charpy V-notch impact energy test method, and hardness test method. The materials shall conform to the required surface finger oxide penetration, interparticle oxide networks, decarburization depth, and nonmetallic inclusion level.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), and1.2.1.8 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 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D8120-17 Standard Test Method for Ferrous Debris Quantification Active 发布日期 :  1970-01-01 实施日期 : 

5.1 By quantifying the concentration of total ferrous debris, this test method provides a direct indication of wear in the machinery by enabling the user to pinpoint when there is a deviation from the normal buildup of ferrous debris shed by the machinery or when the concentration of ferrous debris has exceeded safe operating limits. Specific guidance regarding such procedures may be found in Guides D7669, D7720, and D7874.5.2 This test method can be performed on-site and can be utilized as a particle-size insensitive, minimum sample preparation alternative to laboratory-based screening for abnormal machinery conditions due to the presence of wear debris by means of ferrography as described in Practice D7690, or elemental analysis methods such as atomic emission spectrometry, described in Test Methods D5185 and D6595.1.1 This test method describes a means for quantitative determination of the concentration of ferrous debris in lubricants and greases.1.2 This test method provides a determination of the concentration of ferrous debris in the lubricant or grease from a nominal 0 mg/kg to 10 000 mg/kg (1 % by mass) or greater.1.3 This test method is applicable to all types of lubricating fluids (API Group I-V) and greases sampled from machinery and other mechanical equipment, including reciprocating engine oils, turbine oils, hydraulic oils, gear oils, and bearing greases.1.4 This test method describes a means by which a sample of lubricant or grease is placed in a magnetometer apparatus, which determines the concentration of ferrous debris and provides these readings directly to the operator without further calculation.1.5 This test method is applicable to in-service lubricants and greases at any stage of degradation.1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
