Kennametal Is The World’s Largest Supplier of Genuine Stellite 6B Products
Kennametal’s Stellite 6B (UNS R30016, AMS 5894) is a wrought material with enhanced physical & material properties. The forged microstructure gives Stellite 6B superior toughness and weldability, superior abrasive & erosive wear properties and superior corrosion resistance compared to a cast or welded Stellite 6.
With its excellent wear characteristics, hot hardness, good corrosion resistance and superior mechanical properties, Stellite 6B has been the material of choice in some of the most demanding wear applications. These applications encompass aerospace bearings, steam turbine erosion shields, fan blades, steam turbines, wear plates, tunnel boring seals, gears, sleeves & bushings, drilling and exploration tooling.

Features & Benefits
Resist Seizing & Galling: Stellite 6B is resistant to the effects of seizing or galling. In many cases, its low coefficient of friction allows sliding contact with other metals without damage by metal pick-up. Stellite 6B has been used in equipment where no lubricants were used because of the nature of the product being handled.
Erosive Wear Resistance: Parts made of Stellite 6B have a long service life, even under constant erosive conditions. This material has outstanding resistance to cavitation-erosion. The wrought structure results in improved abrasion wear resistance comparable to much harder cast materials.
Excellent Hot Hardness: Stellite 6B retains high hardness, even at red heat. Once cooled back to room temperature, it recovers its full original hardness.
Impact Resistant: The toughness of the wrought Stellite 6B alloy yields Charpy impact test results 4X that of cast Stellite 6.
Corrosion Performance: Stellite 6B has excellent resistance to a variety of corrosive media. While other materials struggle to survive the harsh corrosive media used in industries like food handling or chemical equipment, Stellite 6B thrives.
Workability: Stellite 6B sheets can be formed and/or welded in place to quickly cover high-wear areas with minimal heat input. It can be fabricated to get you the protection where and when you need it most.
Size Range: Kennametal stocks 6B round bar in diameters 0.312”-6.000” in lengths up to 160” and flat bar/sheet in thickness 0.031”-1.000” in lengths up to 96”. Additionally, 6B can be quoted in custom sizes upon request.
