Benefits of Stellite 6B
Stellite 6B has many benefits across several industries and can be used for the most demanding wear applications. It is particularly valued in aerospace, power generation, and industrial manufacturing. Here are some of the key benefits that Stellite 6B offers:
-
Superior Wear Resistance
- Inherent wear resistance due to chemical composition, not requiring heat treatment. Exceptional resistance to abrasive, erosive, and cavitation wear in the harshest environments.
-
Excellent Hot Hardness
- Retains high hardness even at red heat (approaching 2000°F) and recovers full original hardness upon cooling to room temperature.
-
Seizing & Galling Resistance
- Low coefficient of friction allows sliding contact with other metals without damage, even where lubrication is impractical or impossible.
-
Superior Toughness
- Wrought microstructure provides Charpy impact test results 4X that of cast Stellite 6, offering exceptional impact resistance for demanding applications.
