Invar 36 Forgings Manufacturer, Supplier

Compared to other nickel-iron alloys, Invar 36 Forged Products exhibits a low thermal expansion coefficient. This means that the welded structures must be fully annealed to avoid pitting and flaking. It also has an oxidation scale that increases with heat treatment time. It has nearly constant dimensions at normal atmospheric temperatures and at cryogenic temperatures. Its ultimate tensile strength is obtained in the annealed condition. Invar 36 Forgings has a low coefficient of expansion, near zero, at low temperatures.

It can be forged and swaged, but it is not recommended that it be used in applications where it will be exposed to high-temperature environments. Alternatively, Invar 36 Forgings can be annealed before brazing. Forgings manufactured using Invar 36 are corrosion-resistant and have no CTE. However, a controlled atmospheric heat treatment oven is required in applications that do not require sandblasting. Invar 36 Forgings Products are used in high-precision applications, such as aerospace, telecommunications, solar, and military. It is also used in rod and tube assemblies for temperature regulators. Invar 36 forged rings are essential for carrying liquid gases.
