Abstract

The choice of the chemical composition of new sparingly alloyed high-strength cold-resistant steels with strength level of at least 950 MPa for heavily loaded equipment is substantiated. Thermokinetic diagrams of decomposition of supercooled austenite are plotted for the steels with selected chemical compositions. Heat treatment modes are suggested. The mechanical properties during the heat treatment are determined to develop recommendations for the use of the research results under industrial conditions.
