The proposed technology has been applied to low and medium carbon structural steels. Conventional austenitizing temperature (A{sub c3} + 50{degrees}C) was used. Following the austenitization, the steels were cooled slowly on air or in furnace down to the temperature which was 100 - 210{degrees}C below austenitizing temperature. The steels were then quenched from this temperature to water. The observed microstructures corresponded to those revealed after standard (conventional) quenching. Also the mechanical properties remained unchanged. But the measured internal stresses were found to be lower in comparison to the standard quenching.
