Recommendations on the choice of optimal modes of shot blasting hardening of steel 30HGSN2A (30XГCH2A) according to the criterion of cyclic durability are given. On the basis of experimental studies of the influence of technological parameters and properties of the surface layer, a generalized technological parameter was proposed, including the values of the diameter of the shot and its velocity at 98% coverage of the surface of the part with 4-6 times fraction prints.
