Material Notes:
Applications: Vane plugs, fuel metering pins, spacer bushings, ball bearing blanks, race bearing blanks, diesel engine exhaust, fluid valve seats, saw cutter inserts, wear pads, pins, balls, hardfaces when crack free deposits are not required.Corrosion: Corrosion resistance similar to Stellite alloy 3, but inferior to Stellite alloy 6. Excellent oxidation resistance at low temperatures, but not recommended for reducing environments. Corrosion will vary depending on concentration, temperature, stress, and type of contaminants so exposure tests are recommended.Machinability: Stress relieve before and during machining by holding at 900°C (1650°F) for four hours and slow cool.Wear: High tungsten content results in excellent hot hardness and low stress abrasion resistance superior to Stellite alloy 3. Wear resistance is similar to Stellite alloy 3 and is non-galling when mated with other Stellite alloys.Data provided by the manufacturer, Deloro Stellite Inc.Product of former Deloro Stellite Inc.
