Principal Design Features		A nickel-chromium alloy primarily used as an electric resistance heating element in wire and strip forms. It performs well at generating heat up to approximately 1850 F.

Applications		Heating elements for household appliances.

Machinability		Can be readily machined by conventional means.

Forming		Ductility is good and the alloy may be readily formed by standard methods.

Welding		May be welded by all conventional methods.

Heat Treatment		Anneal at 1950 F to 2000 F and air cool.

Forging		The alloy can be readily forged at temperatures in the 2000 F range.

Hot Working		Hot working may be don in the 1900 F to 1400 F range.

Cold Working		The alloy has good ductility and may be readily cold worked. It will harden due to cold working.

Annealing		Anneal at 1950 F - 2000 F and air cool.

Hardening		Hardens by cold working only.

Other Physical Props		The alloy increases in electrical resistance with temperature. Typical is a 9% increase at 1200 F over room temperature resistance.
