Metco 1220B is similar to Stellite 6 that has a finer than Metco 1220A. Deposits applied using laser cladding or PTA resist seizing, galling and cavitation over a wide temperature range, and combat adhesive, abrasive or erosive wear combined with corrosion at relatively high temperatures. They resist oxidation at temperatures up to 1000 °C (1800 °F) and resist oxidizing acids depending on the acid concentration and temperature. Self-mating surfaces have a low friction coefficient (≈ 0.12).
