ASTM F1684/ UNS K93600/ W.NR:1.3912/ Nilo 36/GB 4J36 Invar alloy
Invar 36 / ASTM F1684 is also know as W.NR 1.3912,UNS K93600,UNS K93601,AWS 090,Invar alloy,ASTM F1684,Alloy 36,W.NR:1.3912 (FeNi36),Ni 36.
4 j36 is a low coefficient of expansion of special low expansion iron nickel alloy. The control of carbon and manganese is very important. Cold deformation can reduce thermal expansion coefficient, in certain temperature range of heat treatment can make the thermal expansion coefficient of stabilization. At room temperature dry 4 j36 has corrosion resistance in the air. In other conditions, such as moisture in the air, is likely to occur corrosion (rust)
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.
