This alloy has the following properties:
4J36 is a special low expansion Fe Ni alloy with ultra-low expansion coefficient. Cold deformation can reduce the coefficient of thermal expansion, and heat treatment in a specific temperature range can stabilize the coefficient of thermal expansion. 4J36 has corrosion resistance in dry air at room temperature. In other harsh environments, such as humid air, corrosion (rust) can occur. It has very low coefficient of thermal expansion and good plasticity and toughness between - 250 ℃ and + 200 ℃
Metallographic structure of 4J36:
4J36 alloy is austenitic
