This specification covers stainless steel powder metallurgy (PM) structural components with minimum densities that are fabricated from prealloyed powder consisting primarily of iron, chromium, nickel, molybdenum, and boron2 and are intended for use in corrosive service. Structural components shall be made by cold pressing and sintering prealloyed powder. The chemical composition; physical properties such as density; and mechanical properties such as tensile strength, elongation and hardness; are detailed.
1.1 This specification covers stainless steel powder metallurgy (PM) structural components with a 7.7-g/cm3 minimum density that are fabricated from prealloyed powder consisting primarily of iron, chromium, nickel, molybdenum, and boron2 and are intended for use in corrosive service.
1.2 With the exception of the values for density and the mass used to determine density, for which the use of the gram per cubic centimetre (g/cm3) and gram (g) units is the longstanding industry practice, the values in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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.
