Al in CA6NM martensitic stainless steel
First of all, as a deoxidizer, we often add Al in CA6NM stainless 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.

The role of AI 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.
