摘要：

The experimental data and the mathematical models obtained for the dependence of the yield strength of building steels on the test temperature at its negative values are analyzed. The well-known methods of calculating the temperature-induced hardening are shown to give a significant error. A mathematical model is proposed for the dependence of the yield strengths of low-carbon and low-alloy building steels on a negative climatic temperature.
