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 Rc42-49, 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.
