Stellite 6 Polystel 6 Hoganas 2537 Hard Facing Rod Red Color Extrusion Screws Flights Tong Bits
Product Description
WL-Co6 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. WL-Co6 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.
Another similar type is Co 6H rod, which has higher hardness.
