VACUUM HEAT TREATMENT OF HIGH ALLOY CORROSION-RESISTANT STEELS
The influence of the high pressure gas quenching on the structure and properties of some high-corrosion-resistant steels was studied. It is shown, that the influence of the tempering temperature on the structure and properties of these steels at this conditions is very significant. The graphical representation of the hardness with tempering temperature is revealed. The most effective temperature ranges that achieve the desired properties are defined. A comparative analysis of the structure and the properties after hardening and high pressure gas in the oil carried out. It is shown that the microstructure and properties of the steel after hardening high pressure gas hardly differ from those after quenching in oil.
