摘要（英）：

The invention relates to a high-strength tough non-magnetic alloy and a preparation method thereof, and belongs to the technical field of austenitic alloy. The alloy comprises the following chemical components in percentage by weight: 0.14-0.30% of C, 0.15-0.80% of Si, 20.00-27.00% of Mn, 0.60-2.00% of Ni, 12.50-19.00% of Cr, 0.60-2.50% of one or two elements of Mo and W, 0.8 to [0.1 * Mn (%) -0.5]% of V, one or two elements of Ti and Nb which can partially replace V with the additive amount controlled within 0.6%, 0.20-0.50% of N, 0.003-0.05% of one or two of Ca and rare earth element, less than or equal to 0.03% of S, less than or equal to 0.03% of P and the balance of Fe. The invention has the advantages that the cost of the raw material is low, the production technology is simple, and the non-magnetic performance and the resistance to intergranular corrosion are stable.
