Depending on applications, would you consider hardfacing?
Materials are generally selected depending on work conditions and on the type of abrasion or wear caused by the other materials in contact.
The basic rules apply.
Cold worked materials will have improved gall resistance.
Always try to mate dissimilar metals.
Both metals must be fully corrosion resistant in the environment.
The high Mn austenitic grades and duplex grades tend to be better at galling resistance. You need to select a specific alloy based on corrosion resistance.

Rust never sleeps
Neither should your protection
Cronidur type steels have proven pretty useful in many applications from clean (like precision spindle bearings) and to terrible (ballscrews in landing gear and other aircraft apps).
