MPIF Standard 35, Materials Standards for PM Structural Parts – 2012 Edition has been revised and expanded. The publication, developed by the powder metallurgy (PM) commercial parts manufacturing industry, covers the latest engineering property data and information available in order to specify materials for structural parts made by the PM process.The MPIF says that publication of the 2012 Edition of this standard renders the 2009 Edition (and prior editions) obsolete. Previous editions should no longer be distributed but destroyed.The 2012 Edition contains new materials & mechanical property data including:Prealloyed Steel FL-5108, as-sinteredHybrid Low-Alloy SteelFLN2-3905, as-sintered and heat treated Diffusion-Alloyed Steel FD-0105, as-sintered and heat treated 400 Series Stainless Steel – as-sintered SS-409LESS-409LNiOther new or revised data covering:Soft Magnetic AlloysFatigue limit values for the FY-4500 materialHybrid Low-Alloy SteelFLN4-4405, heat treated: revised minimum and ultimate strength values400 Series Stainless SteelRevisions to chemical composition table for the SS-409L, -409LE and -434LCb materialsNew or revised engineering information covering:Hardenability (Jominy) DataNew - Hybrid Low-Alloy Steel: FLN2-3905New - Diffusion-Alloyed Steel: FD-0105New - Austenitizing Temperature Information (Key) for all materials listed Strain-Controlled Fatigue – New SectionInformation & DataCoefficient of Thermal Expansion (CTE)New - CT-1000 dataNew and revised verbiage throughout the standard and an updated index.
