Principal Features<\/h2>\n\n\n\n

HAYNES\u00ae<\/sup>\u00a0263 alloy (UNS N07263) is an age-hardenable nickel-cobalt-chromium-molybdenum alloy developed specifically to combine good age-hardened strength properties with excellent fabrication characteristics in the annealed condition. HAYNES\u00ae<\/sup>\u00a0263 alloy exhibits excellent intermediate temperature tensile ductility, and is not normally subject to strain age cracking problems common for gamma prime strengthened alloys.\u00a0 Its strength at elevated temperature is not quite as high as materials such as HAYNES\u00ae<\/sup>\u00a0282\u00ae<\/sup>\u00a0alloy, Waspaloy alloy, or R-41 alloy.\u00a0 However, it is much easier to form or weld than Waspaloy alloy and R-41 alloy.\u00a0 Because HAYNES\u00ae<\/sup>\u00a0282\u00ae<\/sup>\u00a0alloy exhibits superior tensile, creep-rupture, and low cycle fatigue strength than HAYNES\u00ae<\/sup>\u00a0263 alloy and has significantly greater fabricability than Waspaloy and R-41 alloys, it is replacing HAYNES\u00ae<\/sup>\u00a0263 alloy in many applications.<\/p>\n\n\n\n

HAYNES\u00ae<\/sup>\u00a0263 alloy is normally used for applications up to about 1650\u00b0F (900\u00b0C). Its oxidation resistance is comparable to that for other gamma-prime-strengthened superalloys.<\/p>\n\n\n\n

Applications<\/h3>\n\n\n\n

HAYNES\u00ae<\/sup>\u00a0263 alloy combines properties which make it suitable for a variety of fabricated component applications in both aircraft turbine engine and industrial turbine applications. These include low-temperature combustors, transition liners, and some ring components.<\/p>\n\n\n\n
