Xunshi 6B alloy(UNS R30016, AMS 5894) is produced through Powder Metallurgy Process. It has enhanced physical & material properties. The material has equal properties as forged Stellite 6B in 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.

Xunshi 6B alloy has outstanding resistance to most types of wear. Its wear resistance is inherent and not the result of cold working, heat treating or any other method. This inherent property reduces the amount of heat treating and post machining.
6B has outstanding resistance to cavitation erosion. Steam turbine erosion shields from 6B have protected the blades of turbines for years of continuous service. 6B has good impact and thermal shock resistance resists heat and oxidation, retains high hardness even at red heat (when cooled, recovers full original hardness) and has resistance to a variety of corrosive media. 6B is useful where both wear and corrosion
resistance are needed.
