Invar 36(Fe-Ni)

1. Introduce – Ni-Fe alloy with 36% Ni content – Low thermal expansion alloy with a thermal expansion rate of about 1/10 of that of carbon steel in the temperature range of about -250~200℃→ Invar36 Coefficient of Thermal Expansion (CTE) : Close to zero – Common name : Invar 36, FeNi36 – UNS K93600 or K93603 * Invar (1) Meaning : Little change in expansion or contraction with temperature change, so called invariant steel (2) Features : Excellent corrosion resistance, extremely low coefficient of expansion, little dimensional change with temperature (3) Types : Invar36, I...
