In the Metal Injection Moulding (MIM) industry, 17-4 PH stainless steel is one of the most popular materials thanks to its combination of strength, hardness and corrosion resistance. As a result of its success in MIM, it is also attracting interest for use in the growing number of ‘MIM-like’ Additive Manufacturing processes, including binder jetting and feedstock extrusion.

Despite the alloy’s popularity, there remain limited data on the final properties that can be expected, as well as data relating to dimensional control and the impact of Hot Isostatic Pressing. In a major 28-page report published in the latest issue of PIM International, Prof Randall German highlights best practice in the debinding and sintering of 17-4 PH, as well as presenting in-depth analysis of published data.

Sections of this free-to-access report include:

  • An introduction to 17-4 PH
  • Binder and debinding effects
  • Powder characteristics
  • Sintering parameter effects
  • Additives
  • Carbon control
  • Hot Isostatic Pressing
  • Heat treatment
  • Microstructure
  • Mechanical properties
  • Corrosion, wear and biocompatibility
  • Dimensional control
