Stellite 19 Alloy

Stellite 19 is resistant to severe shock and has excellent red-hardness for applications such as cutting tools, machinery parts, high-temperature bearing races, nozzle discs, and burnishing rollers.

One of the outstanding properties of Stellite 19 is its ability to remain hard at red heat. This denotes a range of temperatures from 932 to 1562°F. Stellite 19 has impact resistance that is comparable to high-speed steels but has much higher red hardness. Stellite 19 can be used at higher speeds than high-speed steels. Its excellent resistance to corrosion from many common chemicals combined with its abrasion-resistant qualities makes the use of this alloy economical for machining such materials as plastics and rubber, which liberate corrosives that are used in their manufacture.
