The invention discloses a high-frequency induction selective tempering heat treatment method for high-nitrogen stainless bearing steel, and belongs to the technical field of material heat treatment. The high-nitrogen stainless bearing steel comprises the components in percentage by weight: 0.3-0.65% of C, less than or equal to 1.0% of Si, less than or equal to 1.0% of Mn, less than or equal to 0.015% of S, less than or equal to 0.025% of P, 14.5-16.0% of Cr, 0.85-1.10% of Mo, 0.2-0.5% of N, and the balance Fe, except unavoidable impurity elements. The high-nitrogen stainless bearing steel is subjected to overall quenching and tempering as well as high-frequency induction selective tempering, so that the thread part of a high-nitrogen stainless bearing steel part is locally softened after heat treatment, the hardness requirement of 38-42 HRC is met, meanwhile, the high hardness of 58 HRC or above is kept on the raceway working face, and the use requirement of the bearing part is met. The high-frequency induction selective tempering heat treatment method has the advantages that the problem of integral hardening of the high-nitrogen stainless bearing steel is solved, the high hardness of the raceway working surface is ensured, and the thread part has good strength and toughness in a matching mode.
