New material property data to MPIF Standard 35

July 5, 2021

The Metal Powders Industries Federation (MPIF) has released new material property data for MIM-420 HIP’d & HT stainless steel as an addendum to the existing MPIF Standard 35 from the 2018 edition of ‘Materials Standards for Metal Injection Molded Parts.’

The new data provides minimum and typical mechanical property data tables in both inch-pound and SI units. These datasets were taken from MIM-420 parts HIP’D at 1121°C (+/- 14°C), 103.4 MPa (15,000 psi) [+/- 3.5 MPa (500 psi)] for 4 hours (+15 mins/-0 mins). Heat treatment was vacuum hardening at 1010°C, pressure quench in nitrogen and temper at 205°C for 1 hour.

The Standard Test Methods for Metal Powders and Powder Metallurgy Products have been developed to provide guidance for the industry, adopted in cooperation with member trade associations through committees comprised of technical experts. These committees develop standards within their respective areas of expertise and propose them to the MPIF membership, who must wholly approve the standard before its official adoption. The standards have all been adopted under this procedure.

The addendum is posted on the MPIF website as a PDF, where it will be hosted until the release of the next published edition of the standards document. The files may be included on specification prints and/or sent to those who specify MIM parts.
