Nickel Alloy C-263, Hastelloy® C-263

Hastelloy C-263, is an age hardenable nickel-cobalt-chromium-molybdenum alloy. Also known as Nickel Alloy C-263 and Haynes® 263, Hastelloy® 2 C-263 has some very positive attributes that make it ideal for a wide range of applications.  These attributes include:

  • Very good aged strength properties
  • Excellent fabrication characteristics in the annealed condition
  • Good ductility, formability, and weldability
  • Intermediate temperature tensile ductility
  • Hot working temp range from 1750° to 2100° F (955°-1150° C)
  • Can easily be welding using methods including TIG, MIG, electron beam and resistance welding

In order to be considered Hastelloy C-263, an alloy must have a chemical composition of:

  • Ni 51%
  • Cr 20%
  • Co 20%
  • Ti 2.15%
  • Al .45%
  • C .060%

A number of different critical industries rely on Hastelloy C-263 and Nickel Alloy C-263 for their applications including:

  • Aircraft and Land-based turbine applications
