Invar 36ㅣUNS K93600, K93603

1. Introduce – A Ni-Fe alloy with a nickel content of approximately 36%, known as Invar 36 or FeNi36 – A low-thermal-expansion alloy that exhibits a thermal expansion coefficient approximately one-tenth that of carbon steel at temperatures ranging from approximately -250 to 200°C (Invar 36 coefficient of thermal expansion (CTE): close to 0) * Invar √ Meaning: Known as “invariable steel” because it exhibits virtually no expansion or contraction in response to temperature changes √ Characteristics: Moderate corrosion resistance (Requires surface protection in corrosive or humid envir...
