摘要：
Actual temperatures of structural and phase transformations Ar3 and Ar1 for different chemical compositions of low-alloy pipe steels are determined on the basis of dilatometric studies. Equations are obtained for calculating the temperature of critical points Ar3 and Ar1 taking account of the effect of 14 main chemical elements as a result of processing experimental data. It is shown that Ar3 and Ar1 temperatures calculated by well-known equations differ (by 10–80°C) considerably from actual temperatures, whereas the relationships proposed increase the precision of critical temperature calculation for low-alloy steels by 10°C at least.
