The Metal Powder Industries Federation (MPIF) has released the 2018 edition of its ‘MPIF Standard 35 – Materials Standards for PM Structural Parts’. This standard aims to provide design and materials engineers with the latest engineering property data and information available to specify materials for structural Powder Metallurgy parts.
This revised and expanded standard is said to have been developed by the Powder Metallurgy commercial parts manufacturing industry and includes new data for the AC-2014-T8 aluminium alloy as well as four heat-treated prealloyed steels: FL-3905, FL-4005, FL-4805 and FL-4905. It also includes data on hardenability (Jominy), strain-controlled fatigue and CTE data, and the steam oxidation of ferrous PM materials.
This standard does not apply to materials for PM self-lubricating bearings, powder forged or metal injection moulded products, which are covered in separate editions of MPIF Standard 35.
