Iron nickel alloy invar 36 / 4j36 Plate For Thermostats
Introduction of Invar alloy/4J36/UNS k93600
A Nickel Iron,low expansion alloy containing 36% Nickel.It maintains nearly constant dimensions over the range of normal atmospheric temperatures and has a low coefficient of expansion from cryogenic temperatures to about 500 degree.Nilo 36 also retains good strength and toughness at cryogenic temperatures.Applications include standards of length,thermostat rods,laser components and tanks and piping for the storage and transportation of liquefied gasses.
Chemical Composion
Note:
1.Under condition that the average coefficient of the linear expansion meets the requirements of the standard,the content of nickel and cobalt are allowed to deviate from the stated range.
2.The shape and dimensions of the alloys are in compliance with GB/T14985.
