A STEEL COMPOSITION FOR THE PRODUCTION OF COLD ROLLED MULTIPHASE STEEL PRODUCTS |
摘要 |
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 compositi on being characterised by a specific addition of phosphorus. The latter is adde d in order to reach the desired mechanical properties (high tensile strength i n combination with high elongation) while keeping a good weldability by sufficiently reducing the carbon content. The invention is further related t o a process for producing a steel product, and to said steel product obtained, said product having the composition of the invention.
