1. After high-temperature thermomechanical treatment of 55S2 steel alloyed with chromium, moblydenum, tungsten, and vanadium, the strength and the yield point are increased by 15–30 kg/mm2 and the plasticity is increased 1.5–3 times; the higher the austenization temperature (900–1050°C) the higher the plasticity. 2. The hardening of the steels as the result of HTTMT with low and medium reduction lasts through high-temperature tempering. For elastic components a tempering temperature of 350–400°C is recommended. 3. The recrystallization of austenite in 55S2 steel occurs comparatively rapidly in the process of HTTMT. With increasing degrees and temperatures of deformation this process is accelerated. When 55S2 steel is alloyed with chromium, molybdenum, tungsten, and vanadium, the rate of recrystallization decreases 4–10 times, which favors the use of HTTMT for parts of considerable size.
