Haynes 263 nickel alloy pipe, UNS N07263 nickel bar, Haynes 263 plate supplier

Short Description:

HAYNES 263 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 263 alloy exhibits excellent intermediate temperature tensile ductility, and is not normally subject to strain age cracking problems common for gamma prime strengthened alloys.  Its strength at elevated temperature is not quite as high as materials such as HAYNES 282 alloy, Waspaloy alloy, or R-41 alloy.  However, it is much easier to form or weld than Waspaloy alloy and R-41 alloy.  Because HAYNES 282 alloy exhibits superior tensile, creep-rupture, and low cycle fatigue strength than HAYNES 263 alloy and has significantly greater fabricability than Waspaloy and R-41 alloys, it is replacing HAYNES 263 alloy in many applications.
HAYNES 263 alloy is normally used for applications up to about 1650°F (900°C). Its oxidation resistance is comparable to that for other gamma-prime-strengthened superalloys.
