17-4 PH stainless steel: A guide for debinding and sintering of MIM-type AM processes has been published

In the metal injection molding (MIM) industry, 17-4 PH stainless steel is one of the most popular materials because it combines strength, hardness, and corrosion resistance. Because of its success in MIM, it has also attracted more and more "MIM-like" additive manufacturing processes, including adhesive injection and raw material extrusion.

Despite the alloy’s popularity, it can still be expected that data on the final properties are limited, as well as data related to the effects of dimensional control and hot isostatic pressing. In a 28-page main report published in the latest issue of PIM International, Professor Randall German emphasized the best practice of 17-4 PH debinding and sintering, and conducted an in-depth analysis of the published data.
