Rulon Bearings

Haynes 242® alloy, bar and rings, annealed and aged
Categories: Metal; Nonferrous Metal; Nickel Alloy; Superalloy

Material Notes: Age-hardenable, high ductility in the aged condition, lower thermal expansion than most alloys, very good oxidation resistance up to 815°C, excellent low cycle fatigue properties, very good thermal stability, and resistance to high-temperature fluorine and fluoride environments. Applications include seal rings, containment rings, duct segments, casings, fasteners, rocket nozzles, pumps, hydrofluoric acid vapor containing processes, fluoroelastomer process equipment such as extrusion screws.
