Abstract
A method of complete bainite hardening of steel for use in bearings and other load carrying components, wherein bainite transformation is performed at a temperature just above the martensite formation temperature, transforming 25%-99% of the austenite into bainite at said temperature, and then increasing the temperature to speed up the transformation of the remaining austenite into bainite.

A method of complete bainite hardening of an austenized steel for use in bearings and other load carrying components, consisting essentially of heat-treating a steel at a temperature just above the martensite formation temperature, transforming 25%-99% of the austenite into bainite at said temperature, and then increasing the temperature to speed up the transformation of the remaining austenite into bainite.
