The invention belongs to the technical field of alloy materials, and in particular relates to a novel high temperature resistant Cl ‑ Corroded nitrogen-containing low-nickel alloy and preparation method. A new type of high temperature resistant Cl ‑ The corroded nitrogen-containing low-nickel alloy, measured by mass percentage, comprises the following components: Ni: 42.0-46.0wt%, Cr: 20.0-26.0wt%, Mn: 7.0-8.0wt%, Si: 1.6wt% and below, Mo: 6.0‑8.0wt%, Cu: 0.5wt% or less, Co: 0.8‑1.0wt%, N: 0.12‑0.21wt%, Ti+Al=2.8‑3.0wt%; Ti / Al=1.0‑1.3, Nb: 6-7%, W: 2.0-3.0wt%, V: 1.25-1.55wt%, and the rest are Fe and inevitable impurities. The optimization of the alloy composition of the present invention enables the nitrogen-containing low-nickel alloy to have excellent Cl resistance at high temperature ‑ Corrosive, can replace Inconel 625 alloy, used in high temperature, high pressure chemical, energy and marine engineering fields, such as facing 900 ℃, Cl ‑ Corrosion of the energy storage medium in the solar heat storage tube.
