Conclusions
-
1.
Investigations showed that ordinary heat treatment (in which the article is kept for a certain time at the heat treatment temperature) can be replaced with rapid heat treatment in the case of thin-walled articles of 36G2S steel.
-
2.
It was found that 36G2S steel is strengthened more by rapid heat treatment than by ordinary heat treatment, the quenching and tempering temperatures being the same.
-
3.
The data on the variation of the mechanical properties with the parameters of rapid heat treatment (temperature and heating rate) make it possible to choose the optimum heat treatment conditions to obtain the desired properties in the steel.
