Specification
UNS: K93600
W.Nr:1.3912
Characteristic:
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:
invar 36 has a low coefficient of expansion from cryogenic temperatures to about 260°C. It is also retains good strength and toughness at cryogenic temperatures.
invar 36 is used to making aerospace composites, standards of length, measuring devices, thermostat rods, laser components, clock pendulums and tanks and piping for the storage and transportation of liquefied gases.
Metallurgical structure
Invar 36 is the face centered cubic lattice structure
Corrosion resistance
Invar 36 has corrosion resistance in the dry air of room temperature.In other harsh environments, such as the humid air, there may be corrosion (rust).
Applied field:
Invar 36 suit for need to apply ultra-low coefficient of heat expansion environment.Typical applications are as follows:
1.Liquefied gas production, storage and transport
2.The measurement and control instruments work temperature lower than 200ºC, such as temperature regulating device
3.Metals and other materials use the screw connector bush
4.Bimetal and bimetallic temperature controller
5.Film framework
6.Shadow mask
7.CRP components of the aviation industry temper Die
8.lower than -200ºC the satellite and missile electronic control unit framework
9.The auxiliary tube of the electromagnetic lens in the laser control device
