MIM 17-4 PH Stainless Steel: Processing, properties and best practice
In the Metal Injection Moulding 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 the following article, 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.

Cost-effective Hot Isostatic Pressing: A cost calculation study for MIM parts
Hot Isostatic Pressing (HIP) has become an important post-processing option for the Metal Injection Moulding industry. Whilst the majority of MIM components do not require HIPing in order to meet performance specifications, high-performance applications in the automotive and aerospace sector rely on HIP to remove residual porosity.
The use of HIP is also common for aesthetic applications, where reduced porosity delivers improved polishability. Magnus Ahlfors and colleagues from Quintus Technologies AB present cost calculations for the HIP of a MIM turbocharger impeller, along with the pros and cons of purchasing a HIP system.
