The invention discloses a preparation method of a Hastelloy C-276 precise base band for high-temperature superconducting and the Hastelloy C-276 precise base band, and relates to the technical field of alloy materials, and the Hastelloy C-276 precise base band is obtained after cast ingot smelting, forging and raw material forming, first rolling process, second rolling process, withdrawal and straightening, finished product rolling process, cleaning and polishing are conducted in sequence. According to the preparation technology, the work hardening phenomenon of C-276 can be effectively relieved, mass production of the precise base band with the thickness smaller than or equal to 50 microns is achieved, the width of the rolled base band can be directly suitable for preparation of a second-generation high-temperature superconducting strip, the product has excellent surface performance and mechanical performance, and the product performance is as follows: the hardness is larger than or equal to 200 HV, the room
