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.

| Applications |
Steam turbine erosion shields, Chain saw guide bars, High temperature bearings, Furnace fan blades, Valve stems, Food processing equipment, Needle valves, Centrifuge liners, Hot extrusion dies, Forming dies, Nozzles, Extruder screws & many other Misc. wear surfaces. Applications for alloy 6BH also include tile making machines, rock crushing rollers and cement and steel mill equipment. Alloy 6BH is well suited for valve parts, pump plungers Wrought alloy 6BH offers the fatigue resistance and toughness of a hot worked microstructure, with the heat corrosion and wear resistance of cobalt based alloy. High Performance Alloys, Inc. inventories sheet, and plate. Bar is can be produced 1/2" through 2-1/2" diameter. Bar can be supplied in random lengths or cut to order. Sheet and plate are offered as whole plates, can be abrasive cut, or processed further using water jet services. |

| Additional Information |
Other non-critical uses include tire cloth and rubber cutting, carpet cutting, trimming knives for ceramics, leather knives, and surgical blades. Cobalt 6BH is the same composition of Cobalt 6B, except the material is hot rolled and then age hardened. The direct age-hardening after hot rolling provides the maximum hardness and wear resistance. The advantages this creates are increased wear life, retained edge characteristics, and increased hardness. These properties are in addition to the galling and seizing resistance of the regular Cobalt 6B. Cobalt 6BH is known in the industry as a metal that retains its cutting edge. The economic advantages are in its long wear time, less down time, and fewer replacements. This material surpasses 6K with better ductility, with the same good hardness. |
