WIRE - Haynes^® 263 Alloy

UNS N07263

DESCRIPTION

Haynes® 263 alloy is an age-hardenable Ni-Co-Cr-Mo alloy designed to combine very good aged strength with excellent fabrication characteristics in the annealed condition. While its strength at high temperature is not quite as high as Waspaloy or R-41, it is far easier to form or weld than these alloys. Haynes® 263 exhibits excellent intermediate temperature tensile ductility and is not normally subject to strain age cracking problems common for gamma prime strengthened alloys. In many applications, Haynes® 282® has replaced Haynes® 263 due to its superior mechanical properties and further improved fabricability.
