Analysis of heat treatment parameters of 60Si2CrV steel to enhance the mechanical properties of elastic structural elements

The article analyzes how the temperature of the quenching medium during heat treatment influences the mechanical properties of spring steel grade 60Si2CrV. It presents the correlations between the quenching medium temperature and such parameters as hardness, tensile strength, and elongation. The study identifies the optimal cooling medium temperature range to be 20-30 °C, which ensures enhanced mechanical performance of the steel. The findings can be applied to improve the heat treatment processes of cylindrical springs used in freight wagons, thereby increasing their service life and operational reliability
