Invar 36 as also known as W.NR 1.3912,UNS K93600,UNS K93601,AWS 090,Nilo 36,Invar alloy,ASTM F1684,W.NR:1.3912 (FeNi36) .

A Nickel-Iron, low expansion alloy containing 36% Nickel. It maintains near constant dimensions over the range of normal atmospheric temperatures and has a low coefficient of expansion from cryogenic temperatures to about 500oC (930oF). Nilo 36 also retains good strength and toughness at cryogenic temperatures.

Invar 36 specification: Plate, sheet, strip, rod, bar, wire.

Looking forward to co-operating with you!
