Stainless-steel components represent a large part of the market for sintered parts; they can be produced using many technologies and have a wide variety of applications such as automotive, biomedical industries, mechanical and fashion.

In this article we are going to discuss how sintering parameters, and especially the sintering atmosphere, may affect the quality achievable from sintered stainless-steel parts.
We’ll analyse the three gas options, and we’ll see that in some circumstances there are interesting alternatives that can fit your needs. Read on!
