Description: AFM #6 Cobalt is our most popular and useful cobalt alloy, offering excellent balance between impact, heat, corrosion and metal-to-metal abrasion resistance. It offers outstanding anti-galling properties, superior high temperature hardness and resistance to cavitation erosion making it perfect to use as valve trim in steam engines or repairing worn machine parts. It is ideal for many hardsurfacing applications because of its resistance to mechanical and chemical degradation at extreme temperatures.
Typical Applications: High pressure-high temperature valves, agitators, chain saw bars, digestors, hot oil pump parts, extruder screws, scraper knives, hot trimming dies, hot punches.
