Stellite™ 6 is a cobalt base alloy that consists of complex carbides in an alloy matrix. It is a wear resistant alloy that has good all-around performance. It is also resistant to galling and corrosion and can retain these properties at high temperatures. It is resistant to different forms of mechanical and chemical degradation over a wide temperature range, and can retain a level of hardness up to 930°F. It corrodes primarily by a pitting mechanism and not by general mass loss in seawater and chloride solutions. Its mass loss in sea water is below 0.05mm per year at 22˚C.

Available in multiple sizes and forms.

Tensile Strength: 850 MPa (Castings)
Yield Strength: 700 MPa (Castings)
Elongation: <1 % (Castings)
Hardness: 36-45 HRC

BAL27-324-60.9-1.4Fe, Si, Ni, Mo, Mn
