Abstrakt: Thermal cycling treatment of 08Kh2G2F and 30KhGSN2A steels with intermediate hardening from intercritical range temperatures (Ac1+20–40°C) provides an ultrafine austenitic grain size of 2.5–3.5 µm. The obtaining of a finer and more uniform structure of these steels in comparison with thermal cycling treatment consisting of three hardenings from the area of the stable state of austenite provides a 1.2–1.4 times higher impact strength at low temperatures.
