Preparation method of austenitic stainless steel part for superconducting magnet

The invention discloses a preparation method of an austenitic stainless steel part for a superconducting magnet. The preparation method comprises the following steps that firstly, an austenitic stainless steel raw material is obtained; 2, cutting the austenitic stainless steel raw material to obtain an austenitic stainless steel blank; thirdly, the austenitic stainless steel blank is subjected to heat treatment, and a heat-treated blank is obtained; and fourthly, the heat treatment blank is machined, and the austenitic stainless steel part is obtained. And fifthly, the austenitic stainless steel part is subjected to vibration treatment. By combining the cutting treatment, heat treatment, machining and vibration treatment processes, the magnetic conductivity of the austenitic stainless steel part is reduced and stabilized within a certain range on the premise of low cost and high efficiency, and the magnetic conductivity design and use requirements of Dewar and parts in superconducting magnet equipment are met
