4J36 Alloy Sheet

Nickel Alloy Invar Plate 4J36 Invar 36 Sheet

1 . Description:

4J36 alloy is also called INVAR alloy. The Curie point of the alloy is about 230℃. Below this temperature, the alloy is ferromagnetic and has a very low expansion coefficient. Above this temperature, the alloy is non-magnetic. , The expansion coefficient increases. The alloy is mainly used to manufacture components with approximately constant dimensions within the range of temperature changes, and is widely used in the radio industry, precision instruments, meters and other industries.

     

4J36 can be welded by oxyacetylene welding, arc welding, electric welding and hydrogen atom welding. Since the coefficient of expansion is related to the chemical composition of the alloy, the alloy composition should be avoided as much as possible due to welding. Therefore, it is best to use argon arc welding. The filler metal for welding should preferably contain 0.5% to 1.5% of titanium to reduce welding pores and crack.

 

 

2 . Heat treatment process

Stress relief annealing
Heat to 530~550℃, keep for 1~2 h. Cool in the furnace
annealing
Heating to 830~880℃ ,keep holding for 30 min. Furnace cooling
Stabilization
(1) Heat to 830 ℃ in a protective atmosphere, hold for 20min. ~ 1h, quench (2)Temper
Precautions
(1) The alloy cannot be hardened by heat treatment
(2)Surface treatment can be sandblasted, polished and pickled
