4J36 is a special low-expansion iron-nickel alloy with ultra-low expansion coefficient. The control of carbon and manganese is very important. Cold deformation can reduce the coefficient of thermal expansion, and heat treatment can stabilize the thermal expansion coefficient within a certain temperature range.

The heat treatment of 4J42 includes stress relief annealing for machined parts, intermediate annealing for hardening during cold rolling, cold drawing and cold stamping, and pre-oxidation of materials before use as sealing materials.
