Also has resistance to some oxidizing environments. Recommended for welding filler metal for general corrosion resistance in many applications
C-22 can easily be cold-worked because of its ductility and cold-forming is the preferred method of forming. More energy is required because the alloy is generally stiffer than austenitic stainless steels. 0.28" thick sheet in the heat-treated at 2050 °F, rapid quenched condition, has an average olsen cup depth of 0.49".

• Cobalt Alloy 6B

HPA Cobalt Alloy 6B (Co-Cr-W) (UNS R30016) Co 59.0, Cr 30.0, W 3.5, Ni 2.5, Mn 1.4, C 1.0

Excellent hot strength, which is fully returned when cooled to room temperature again. Replacement for castings due to better ductility, and dependability for sealing surfaces. Seizing, galling and non-lubricated wear can be minimized by using this alloy. Metal seizing is when one metal piece building heat against another "weld" together. Galling is when these welded areas break off and forms abrasive debris which creates additional abrasion problems, and can lead to other types of corrosion.
Turbine engine nozzle fuel injectors, steam turbine (last vane) to prevent water erosion as the steam condenses. Pump applications such as motor shafts, bushings, sleeves and stems.
Cobalt 6B is cobalt based chromium, tungsten alloy for wear environments where seizing, galling and abrasion are present. 6B is resistant to seizing and galling and with its low coefficient of friction, allows sliding contact with other metals without damage by metal pick up in many cases. Seizing and galling can be minimized in applications without lubrication or where lubrication is impractical. Metal seizing is similar to one metal piece building heat against another and they become "welded" together. Galling is when these "weld" areas break off and form abrasive debris which creates additional abrasion problems.

• Cobalt Alloy 6BH

HPA Cobalt Alloy 6BH (Co-Cr-W) (UNS R30016) Co 59.0, Cr 30.0, W 3.5, Ni 2.5, Mn 1.4, C 1.0

Better ductility than 6K, with hardness of about Rc 42 - 49, makes great knife material. This variation of 6B offers increased wear life due to higher hardness, and retained edge characteristics. Economic advantages are: long wear life, fewer replacements, and less down time.
Food preparation equipment (minimal metal loss), saw blades, scrapper blades, granulates, chippers, shredders and other cutting edges where tool life is a necessity. The F.D.A. has approved for use in food contact due to lower metal loss. Other non-critical uses include tire cloth and rubber cutting, carpet cutting, trimming knives for ceramics, leather knives, and surgical blades.
