STELLITEtm 6 is the most widely used of the wear resistant
cobalt-based alloys and exhibits good all-round performance.
It is regarded as the industry standard for general-purpose wear
resistance applications, has excellent resistance to many forms
of mechanical and chemical degradation over a wide temperature
range, and retains a reasonable level of hardness up to 500°C
(930°F). It also has good resistance to impact and cavitation
erosion. Stellitetm 6 is ideally suited to a variety of hardfacing
processes and can be turned with carbide tooling. Examples
include valve seats and gates, pump shafts and bearings, erosion
shields, and rolling couples. It is often used self-mated.
CORROSION RESISTANCE
The typical electrode potential in sea water at room temperature
is -0.25V (SCE). Like stainless steels, Stellitetm 6 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. More information regarding corrosion
resistance can be provided on request.
