The results of the dilatometric investigation of the phase transformations in ChS-139 steel over the temperature range from 20 to 1 000oС are presented. The error in the coefficient of linear thermal expansion (TCLE) is (1.5–2) · 10–7 К–1. The temperatures of the phase transformations, the changes of relative expansion on mutual austenite-martensite transitions, and TCLE of all phases are determined. An interpretation of a number of specific points in the temperature dependences of the properties is given.

Keywords:
