To ensure the parameters of wheels heat treatment in the conditions of production ("Interpipe NTZ"), the temperature of steel austenitization was lowered from 950 C to 860 C. Such an increased content of silicon and manganese was found to have a negative effect on the fatigue crack resistance and the resistance of contact-fatigue damage formation of the wheel steel, even with reduced carbon content.
