摘要：Provided is a method for manufacturing a blasting material for shot peening

with which a reliably high level of hardness can be achieved while preventing an increasein the material cost. Quenchable steel is used as a material in a blasting materialmanufacturing step (S). After granules () which are quenched by means of a wateratomization method are formed in a quenching step (S), the granules () are temperedinside a heating furnace () at a prescribed temperature (from 130-230° C., and preferablyfrom 160-230° C.) For a prescribed amount of time in a tempering step (S). A workhardening treatment is applied in a work hardening step (S) wherein the granules () areblasted/bombarded onto a target material () to apply stress to the granules () using anapparatus for shot peening ().
