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 welded 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%
