 Characteristic as below:

The higher tungsten content provides better high-temperature properties compared to Stellite 6, and it can be used at temperatures up to about 700˚C.

Processing conditions and application:

Stellite 12 is typically used for Incoloy 800ht£ that need to withstand abrasion, heat and corrosion. Examples include industrial knives for cutting carpets, plastics, paper and synthetic fibres; and saw tips in the timber industry. It is also used for control plates in the beverage industry, pump vanes, bearing bushes and narrowneck glass mold plungers; and for hardfacing of engine valves, pinch rollers in the metal-processing industries, and rotor blade edges.
