Invar 36 is used where high dimensional stability is required,such as precision insturmrent,such as precision instruments,clocks,seismic

creep gauges,television shadow-mask frames,valves in motors,and antimagnetic watches.In land surveying,when first-order (high-precision) 

elevation leveling is to be performed,the level staff (leveling rod) used is made of Invar,instead of wood,fiberglass,or other metals.Invar struts were used in some pistons to limit their thermal expansion inside their cylinders.

The heat treatment process 

Annealing for stress relief

Heated to 530~550℃ and hold 1~2 hours.Cold down 

 

Annealing

In order to eliminate hardening,which can be bring out in cold-rolled,cold drawing process.Annealing needs heated to 830~880℃

in vacuum,hold 30min.

 

The stabilization process 

1.In protrective media and heated to 830℃,hold 20mins.~1h,quench 

2.Due to the stress generated by quenching,heated to 315℃,hold 1~4h

 

Precautions 

1.Can not be hardened by heat treatment 

2.Surface treatment can be sandblasting,polishing or pickling

3.Alloy can be used 25% hydrochloric acid picking solution at 10℃ to clear oxidized surface.
