The deformation behavior of tensile tested corrosion resistant high-chromium steel electrically saturated with hydrogen has been investigated. The studies were performed for high-temperature tempered steel with sorbitic structure and after electrolytic hydrogenation for 6 and 12 hours. It was found that hydrogen has markedly reduced the breaking stress and elongation leading to the fracture of the specimen. Using the method of double-exposed speckle photography, it was found that the plastic flow of the material had localized character. The evolution of localized-strain center distributions follows the law of plastic flow. The autowave parameters (autowave velocity and autowave length) were measured for every state of high-chromium steel under investigation and the difference between them is of great significance.
