The process of creation and subsequent hardening of a gradient carburized layer in low-carbon martensitic steel 17Kh2G2NMFTB is studied. It is shown that the structure and properties of the carburized layer can be optimized due to formation of reverted austenite hardened by quenching from the intercritical temperature range.
