The Metal Powder Industries Federation (MPIF) has published the 2009 edition of MPIF Standard 35, Materials Standards for PM Structural Parts. This most recent version of the standard has adopted the practice of significant figures usage, and provides the design and materials engineer with the latest engineering property data and information available in order to specify materials for structural parts made by the PM process.
Developed by the powder metallurgy (PM) commercial parts-manufacturing industry, each section of the 84-page standard is clearly distinguished by easy-to-read data tables and explanatory information for each material listed. Detailed explanatory notes and definitions, along with data cited in both Inch–Pound and SI units, help to make the standard more "user friendly."
The standard also includes new information on chemical compositions and mechanical properties of materials such as hybrid low-alloy steels, sinter-hardened steels, 300 series stainless steels, and soft magnetic alloys.
The new standard is available in several versions at a list price of $50: hard-copy printed booklet, CD ROM or PDF electronic format. It can be also purchased online (http://www.mpif.org) along with other MPIF materials standards covering powder-forged steel parts, metal injection molded (MIM) parts, and PM self-lubricating bearings.
