In the article researched spherical head rod of steel 30H3MFA made cold volume punching on the special stamp. Stressed-strained state in the process of forming spherical heads are investigated experimentally-settlement methods of fiber makrostrukturi and measurement of hardness, proportioned used resource of plasticity.
