Wear Resistant Alloys

Wear is said to be second in a failure of a part. First corrosion occurs, then the particles act against the mating surfaces, after severe galling and seizing, the part finally ceases to move, or "freezes up."

HPAlloys is proud to present the following materials. We have also included some materials that exhibit good corrosion-erosion properties.

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 form an 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.

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.

NITRONIC 60® (Alloy 218) (UNS S21800) Fe 63, Cr 17, Mn 8, Ni 8.5, Si 4, N 0.13 High strength fully Austenitic alloy that resists galling and wear. Significantly lower cost to extend part life and lower maintenance. The yield strength is twice that of 304 and 316 stainless steels, in the annealed condition. Tensile strengths can be produced in excess of 200 ksi. Chloride pitting is superior to that of type 316, and the oxidation resistance is similar to type 321 at elevated temperatures, and excellent cryogenic impact strength.
Valve stems, seats, and trim; fastening systems, screening, pins, bushings, roller bearings, pump shafts and rings. Food handling, medical, automotive, aerospace and nuclear.

NITRONIC® 30 Low alloy version of NITRONIC 60, primarily used for abrasion resistance, or corrosion abrasion requirements.

HAYNES® alloy 25 (L605) (UNS R30605) (See main Description in Temperature/Heat Resistant)
