A possibility of using hardening treatment of the stamping tools in high-pressure nitrogen with thermal cycling was analyzed. A thermal field of Kh12MF steel batches under accelerated heating and cooling conditions during thermal cycling was studied. A satisfactory agreement between the experimental and prescribed temperature conditions in the central and peripheral batch regions has been established. A thermal cycling with subsequent quenching was shown to have a positive effect on the structure, hardness, and impact toughness of steel.
