Invar 36 seamless pipe / tube , FeNi alloy , W. Nr.1.3912 seamless
Invar 36, also known as FeNi36, is a nickel-iron, low-expansion alloy containing 36% nickel. It
has a low coefficient of expansion from cryogenic temperatures to
about 260°C. In the dry air at home temperature, invar 36 has good
resistance to corrosion. But in moist air, it may go corrosion.
Invar 36 is suitable for the applications who require low coefficient of
expansion, such as production, storage and transportation of liquid
gas, temperature regulation devices working below 200°C, aperture
mask, unit frameworks working below -200°C and so on.
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.

Invar 36 seamless pipe Characteristics:
Invar 36 is an iron-nickel alloy containing 35-36% nickel and
characterized by an extremely low coefficient of thermal expansion
(excellent for applications requiring no dimensional changes with
temperature variations.) Invar is strong, tough, ductile and
possesses a useful degree of corrosion resistance. It is magnetic
in the temperature range up to 400 oF.
Invar 36 seamless pipe 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 200°C, such as temperature regulating device
3.Metals and other materials use the screw connector bush
4.Bimetal and bimetallic temperature controller
7.CRP components of the aviation industry temper Die
8.lower than -200℃ the satellite and missile electronic control
9.The auxiliary tube of the electromagnetic lens in the laser
