As an alloying element, nickel has a positive influence on ductility and rust resistance in steel alloys.
Niobium and tantalum are used as alloying elements in stainless steels and special stainless steels.
The nitratability indicates how strongly a material can be hardened by diffusion of nitrogen.
Nitrogen is a low-reaction gas and is particularly well suited as an inert gas for industry.
