Stellite Alloy Applications Across Industries
Proven performance in the world's most demanding industrial sectors -- where wear, corrosion, extreme heat, erosion, and cavitation require the highest material standards.
Power Generation
Critical wear components for continuous extruders, horizontal extruders, gas turbines, steam turbines, industrial generators, and nuclear power plants operating under extreme heat and erosion.
Oil & Gas
Wear-resistant and corrosion-resistant parts for MWD pulsers, downhole measurement instruments, rod pumps, centrifuges, gate & ball valve seats, and pump bushings in high-pressure corrosive environments.
Steel Industry
Sink rolls, stabilizing rolls, bushings, bearing sleeves, and valve seats for continuous hot-dip galvanizing lines, where molten zinc corrosion and high-temperature wear demand superior alloy performance.
Woodworking
Stellite-tipped saw teeth and cutting inserts for band saws, circular saws, and chainsaws -- delivering longer edge life, reduced resharpening frequency, and superior impact resistance in continuous lumber cutting operations.
Food Processing
Wear-resistant and corrosion-resistant components for centrifuges, homogenizers, and sealers used in food and beverage production, where chemical cleaning agents and abrasive media accelerate component degradation.
Glass Industry
High-temperature alloy tips, bushings, and forming components for glass fiber drawing machines and blow molding equipment, where continuous exposure to molten glass demands exceptional oxidation and wear resistance.
Paper Industry
Cobalt alloy-coated screen discs, centrifuge wear parts, refiner plates, and pump components for pulp and paper processing, where abrasive fiber slurries and chemical environments cause rapid material degradation.
Chemical & Plastics
Wear-resistant liners, screw tips, dies, and cutting heads for extruders, underwater pelletizers, injection molding machines, and extrusion lines. Also corrosion-resistant pump components for aggressive chemical media.
Automotive
Cobalt alloy valve seat inserts, valve guides, and wear-resistant components for intake and exhaust systems in high-performance engines, where thermal cycling and combustion gases demand superior oxidation and wear resistance.
Cross-Industry Wear Conditions
Stellite alloys address multiple simultaneous degradation mechanisms across all industries. Our materials are engineered for the most complex combined-stress environments.
High-Temperature Wear
Components operating above 500°C where conventional alloys lose hardness and fail prematurely.
High-Temperature Corrosion
Oxidation, sulfidation, and hot corrosion in combustion gases, molten metals, and aggressive chemical atmospheres.
High-Pressure Corrosion
Downhole, subsea, and pressurized process environments where corrosive fluids attack component surfaces under extreme mechanical stress.
Wear + Corrosion Combined
Synergistic degradation where simultaneous mechanical wear and chemical attack accelerate material loss beyond what each mechanism causes alone.
