The presented paper is focused on laser shock-peening technology for hardening the metallic material surface. The material surface hardening improve fatigue performance, static properties, and resistance to stress corrosion cracking of metallic material, which is achieved by creating a pressure residual stress with. The hardening is achieved by shock waves, which are generated by confining the laser-induced plasma to cause a large pressure shock wave over a significant surface area. In the present study, effects of laser shock peening (LSP) on static and dynamic mechanical properties of austenitic stainless steel for nuclear industry were investigated. The tested material was austenitic stainless steel GOST 08CH18N10T (AISI 321H-UNS S32109) for nuclear industry (water–water energetic reactors).
