Abstract: The study shows the results of the optimization process of thermal treatment of body parts made of structural type alloyed steel 50HMUA ensuring obtaining of martensite structure not higher than 3÷4 points with hardness not less than 58÷59 HRC. A methodological approach is designed to setting of the mode of quenching in the temperature gradient conditions for the furnace profile. Results have scientific and practical importance in terms of providing high performance indicators for the products made of this steel, and also opportunities for introducing automated quenching process.

Key words: optimization of thermal treatment quality of steel structure martensite troostite grain size operational indicators
