2 EQUIVALENT DESIGNATION
AMS 5894, 60Co-28Cr-4.5W-1.15C, STELLITETM 6B, STELLITETM 6K
3 APPLICATION
These products have been used typically for parts requiring wear resistance and minimum galling or seizing tendencies at room and elevated temperatures, but usage is not limited to such applications.
Whether your application involves high-impact pulp agitators, critical directional drilling tools, or aerospace components, Stellite™ 6B can offer superior wear resistance and the mechanical properties needed to withstand the toughest of applications. Stellite™ 6B meets the requirements of Aerospace Material Specification AMS 5894.
Stellite™ 6B used for steam turbine erosion shields to protect the blades of turbines.
In addition to wear resistance, Stellite™ 6B has good resistance to a variety of corrosive media. This combination of properties makes Stellite™ 6B particularly useful in such applications such as food-handling machinery, chemical equipment and others where both wear and corrosion resistance are necessary.

5 OVERVIEW
Stellite™ 6B
These products have been used typically for parts requiring wear resistance and minimum galling or seizing tendencies at room and elevated temperatures, but usage is not limited to such applications.
Whether your application involves high-impact pulp agitators, critical directional drilling tools, or aerospace components, Stellite™ 6B can offer superior wear resistance and the mechanical properties needed to withstand the toughest of applications. Stellite™ 6B meets the requirements of Aerospace Material Specification AMS 5894. All Stellite™ 6B products are accompanied by full material certifications and are DFARS compliant.
Stellite™ 6B used for steam turbine erosion shields has protected the blades of turbines for over 30 years of continuous service.
In addition to wear resistance, Stellite™ 6B has good resistance to a variety of corrosive media. This combination of properties makes Stellite™ 6B particularly useful in such applications such as food- handling machinery, chemical equipment and others where both wear and corrosion resistance are necessary.
Stellite™ 6K
Stellite™ 6K is excellent for cutting or scraping applications, such as knives or scraper blades.
6 CHARACTERISTICS
6.1 RESIST SEIZING AND 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. Sleeves made of Stellite™ 6B move smoothly, with minimum resistance, even when operating in contact with other metal parts. They have been useful in inaccessible areas where efficient lubrication is impossible. Sleeves and bushings have resisted seizing even when lubricants were diluted by gasoline, cleaning fluids and other liquids that wash out an oil film. They have operated at peak efficiency even when lubricants decomposed under heat or were destroyed by abrasive particles.
6.2 RESIST EROSIVE WEAR
Stellite™ 6B
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. Stellite™ 6B used for steam turbine erosion shields has protected the blades of turbines for over 30 years of continuous service.
6.3 EXCELLENT HOT HARDNESS
Stellite™ 6B retains high hardness, even at red heat. Once cooled back to room temperature, it recovers its full original hardness.
6.4 GOOD IMPACT AND THERMAL SHOCK RESISTANCE
Stellite™ 6B combines wear and corrosion resistance with good impact strength and resistance to thermal shock.
The toughness of the wrought alloy depicted by its charpy impact energy goes up almost four fold compared to the cast version.
6.5 RESIST HEAT AND OXIDATION
High temperatures have little effect on the hardness, toughness and dimensional stability of these alloys. They are highly resistant to atmospheric oxidation at ordinary temperatures and have good resistance to oxidation at elevated temperatures.
6.6 CORROSION RESISTANCE
In addition to wear resistance, Stellite™ 6B has good resistance to a variety of corrosive media. This combination of properties makes Stellite™ 6B particularly useful in such applications such as food- handling machinery, chemical equipment and others where both wear and corrosion resistance are necessary.
