LORK is a super alloy manufacturer with 20 years of manufacturing experience.
Stellite cobalt-based alloys consist of complex carbides in an alloy matrix. They are resistant to wear, galling, and corrosion and retain these properties at high temperatures. Their exceptional wear resistance is due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a CoCr alloy matrix.
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.
Key Features of Stellite 19
High Wear Resistance
Stellite 19 is renowned for its high hardness, which translates to excellent wear resistance. This means that components made from Stellite 19 last longer, even in abrasive conditions.
Superior Red Hardness
A key feature of Stellite 19 is its ability to maintain hardness and strength at high temperatures, much higher than those where high-speed steels begin to soften. This makes Stellite 19 an excellent choice for high-temperature applications.

1239-1299ºC 2263-2370ºF |
Corrosion Resistance
Stellite 19 also offers excellent resistance to corrosion. This makes it ideal for use in environments where components are exposed to corrosive substances, such as in chemical processing or marine applications.
Applications in Various Industries
Stellite 19's unique properties make it versatile for various industries, including manufacturing cutting tools, machinery parts, high-temperature bearing races, and components that need to withstand severe impact and high temperatures. Its ability to endure harsh conditions without significant wear ensures reliability and longevity in critical applications.
Importance in Modern Engineering
The development and use of Stellite 19 have been crucial in advancing modern engineering and manufacturing. Its exceptional performance allows for the creation of durable, high-quality components that operate reliably under extreme conditions, reducing maintenance costs and increasing efficiency.
Conclusion
Stellite 19 represents a significant advancement in material science. Its high wear resistance, red hardness, and corrosion resistance make it essential for industries needing robust and reliable performance in demanding environments.
