This is one of the controlled expansion alloys.It has an expansion rate roughly 10% that of standard carbon steels.Also known as Invar 36

or Alloy 32-6,but this alloy is extremely rare and is generally only produced by the mill in the heat lot quantities.

Note:Recent testing has determined that increased hardness will decrease CTE in all temperature rangs in Invar alloys.


Invar 36 is suitable for the applications who require low coefficient of expansion, such as production, storage and transportation of liquid gas, temperature regulation devices working below 200°C, aperture mask, unit frameworks working below -200°C and so on.

This alloy has been used fro applicaitons where dimensional changes due to temperature variation must be 

minimized such as in radio and electronic devices,aircraft controls,optical and laser system,etc.

Invar 36 alloy has been used in conjunction with high expansion alloys in applicaitons where a motion is desired 

when the temperature changes,such as in bimetallic themromostats and in rod and tubes assemblies for temperature 



Annealing for stress relief 

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



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 

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

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




Can not be hardened by heat treatment 

Surface treratment can be sandblasting,polishing or pickling 

Alloy can be used for 25% hydrochloric acid pickling solution at 70℃ to clear oxidized surface
