Abstract: The present invention is related to a steel product of the weathering steel type, i.e. a product exhibiting increased corrosion resistance after having been exposed to the outside environment for a given time. According to the invention, the steel product is defined by a composition consisting of (in wt %):—Carbon between 0.03 and 0.2,—Manganese between 0.5 and 2,—Copper between 0 and 0.5,—Ti between 0 and 0.1,—Cr between 0 and 0.5,—Nickel between 0 and 0.2,—Niobium between 0 and 0.1,—Nitrogen between 0 and 0.01,—Sulphur between 0 and 0.01, Phosphor between 0 and 0.01,—Aluminium higher than 0 and maximum 1.5,—Silicon between 0.25 and 1.5, the balance being Fe and accidental impurities, and wherein the sum of the Al and Si levels is higher than about 0.85 wt %.

Abstract: The present invention is related to a process comprising a cold rolling step, for the production of uncoated, electro-galvanised or hot dip galvanised TRIP steel products, hot rolling a slab of a specific composition, wherein the finishing rolling temperature is higher than the Ar3 temperature, to form a hot-rolled substrate, cooling said substrate to a coiling temperature (CT) between 500° C. and 680° C., coiling said substrate at said coiling temperature, pickling said substrate to remove the oxides, cold rolling said substrate to obtain a reduction of thickness, with a minimum reduction of 40%.

Abstract: The present invention is related to a steel composition intended to be used in a process including a cold rolling step, for the production of uncoated, electro-galvanized or hot dip galvanized TRIP steel products, the composition being characterized 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 the steel product obtained, said product having the composition of the invention.
