Description:
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.
