Abstract

A method of heat treating a cold rolled steel strip includes soaking a cold rolled steel strip having a specific composition above (Ac3−60)° C. for a certain duration thereby obtaining a cold rolled strip having a partially austenitic microstructure; cooling of the resulting soaked steel strip to a temperature below Ms; heating and heat treating the cooled steel strip in the temperature range of Bs-Ms; and cooling the heat treated steel strip to ambient temperature.
