Abstract

The article describes the use of induction heat treatment for products made of 1.3343 tool steel (analogue R6M5) and 12Cr18Ni10Ti chromium-nickel steel. The changes in the surface morphology parameters as well as in hardness after strengthening heat treatment were studied. The hardness of tool steel after quenching (from 1150–1200 °C) reached 940–1080 HV (9.2–10.8 GPa). During induction treatment (temperature 800 °C and duration not less than 120 s) of 12Cr18Ni10Ti steel, a metal oxide coating with a hardness of at least 9.55±1.97 GPa was formed.
