Development of the Regimes of Chemical Heat Treatment of Gear Wheels from Sparingly Alloyed Steel

Abstract

The new approach to development of regimes of chemical heat treatment of gear wheels from sparingly alloyed steels is offered. The unconditional advantage of sparingly alloyed steel before high-alloy chromium-nickel steel 20ХН3А, widely applied in engineering industry, is displayed.
