Abstract

A method for producing a dual phase ferrite-martensite steel product from a cold rolled stainless steel. The method includes a step of rapidly heating the steel to annealing temperature in less than 30 seconds, followed by a step of cooling the heated steel at a cooling rate sufficient to transform austenite to martensite.
