(57) Abstract :
The present invention is related to a steel composition intended to be used in a process comprising a cold rolling step, for the
production of uncoated, electro-galvanised or hot dip galvanised TRIP steel products, said composition being characterised by a
specific addition of phosphorus. The latter is added in order to reach the desired mechanical properties (high tensile strength in
combination with high elongation) while keeping a good weldability by sufficiently reducing the carbon content. The invention is
further related to a process for producing a steel product, and to said steel product obtained, said product having the composition of the
invention.
