Fe-Cr-Ni and Fe-Cr-C, the Foundation of Stainless Steels

This lecture will review the Fe-Cr diagram and discuss its relevance to stainless steel metallurgy. We will review how modifications to this diagram (through alloying) can allow us to make the various types of stainless steels (martensitic, ferritic, austenitic, duplex, and PH).

The walkthrough below shows how to make the calculations discussed in the lecture.
