What are the heat treatments for stainless steel? Are different types of stainless steel heat treated differently?
The main alloying element is Cr, or a small amount of stable ferrite elements are added, such as Al, Mo, etc., and the structure is ferrite. The strength is not high, and the properties cannot be adjusted by heat treatment. It has a certain plasticity and is relatively brittle. It has good corrosion resistance in oxidizing media (such as nitric acid) and poor corrosion resistance in reducing media.
