Precision Alloy Nickel Iron Steel Invar 36 Nickel Bar Rod

 

1 . Description

36 alloy is a special ultra-low coefficient of heat expansion of low-iron-nickel alloy. One of carbon and manganese element of control is very important. Cold deformation can reduce the coefficient of thermal expansion, in particular within the framework of the heat treatment temperature coefficient of thermal expansion will enable stabilization. Has the following characteristics:

1.Has very low coefficient of heat expansion between the temperature of -250°C and 200°C.

2.Good toughness and plastic

Metallurgical structure

Invar 36 is the face centered cubic lattice structure

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
