UNS K93600, W.Nr. 1.3912
Nilo® 36, also called Invar®, is a low-expansion alloy containing 36% Nickel. The alloy maintains nearly constant dimensions over the range of normal atmospheric temperatures and has a low coefficient of expansion from cryogenic temperatures to about 260°C. Nilo®36 also retains good strength and toughness at cryogenic temperatures. The alloy is used for measuring devices, thermostat rods and for transporting liquefied gases. Recommended filler metal for welding is Nilo® CF36.
