Conclusions 1. After heating to 1100°C and subsequent phase recrystallization to cycles making it possible to obtain an approximately 2 mm case depth in vacuum carburizing the mechanical properties (σt, σy, Ψ, δ) of the investigated steel and also the impact strengtha 1 do not drop with the exception ofa 1, of 20Kh steel, which decreases by 6.7% after heating at 1100°C for 2h. 2. The static bend strength for the steels after vacuum carburizing at 1050°C, hardening with reheating, and low temperature tempering is higher and the impact strength after vacuum carburizing at 1050 and 1100–1250°C not lower than after gas carburizing. 3. The fatigue resistance of the gear teeth after gas and vacuum (1050°C) carburizing is at the same level and the character of fracture of the teeth in fatigue tests is similar.
