The role of alloying elements in CA6NM martensitic stainless steel 6

The role of——Al in CA6NM martensitic stainless steel

 

First of all as a deoxidizer we often add Al element into steel. At the same time Al is also a ferrite forming element. As a result its promoting effect on ferrite formation is about 2.5~3 times of that of Cr.

 

Al element can form a dense Al2O3 film on the surface of steel.As a result it can Improve  the antioxidant capacity of stainless steel.
