Published: 01 August 2004
... Carpenter Invar 36 alloy is a 36% nickel-iron alloy with a rate of thermal expansion approximately one-tenth that of carbon steel at temperatures up to 204 deg C (400 deg F). This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes...

... to thermal expansion. Above 52% Ni in iron, ther- mal expansions are greater than 11 × 10 6/K (6 × 10 6/°F). When the expansion curve for ordinary steel is compared to other alloys, the expansion of Carpenter Invar 36 alloy (see Alloy Digest Fe-131) is only one-sixth that of carbon steel at ordinary...

... be allowed on workpieces to clean up by light grinding or pickling after annealing. Stress relief for sections having light finishing cuts or grinding performed after annealing is accom- plished by heating to 316 427 °C (600 800 °F), for a time to uniformly heat through the workpiece. Weldability: The Invar...
