Steel, steel wire, and process for forming drawn wire of steel

The present invention relates to a process for producing a ferritic stainless steel having an improved corrosion resistance, and especially resistance to intergranular corrosion and to pitting corrosion. The steel is subjected, in a first phase, to cooling at a rate of between 400.degree. C. and 600.degree. C./hour down to a temperature of 900.degree. C. and then, in a second phase, to rapid cooling at a rate of between 1200.degree. C. and 1400.degree. C./h.

Process for producing a ferritic stainless steel having an improved

The method comprises effecting the solidification of the metal in a continuous casting ingot mould constituted by two cooled rolls (2) rotating in opposite directions and disposed in confronting relation so as to define a casting space therebetween, continuously extracting from the ingot mould a solidified steel strip (3), and, below the ingot mould, subjecting the strip to a quenching medium (6) so as to cool it sufficiently rapidly to prevent formation of austenite. This medium may be formed by a quenching bath placed in a container (4) disposed under the rolls (2) and having a bottom provided with an opening (5) for the passage of the solidified strip (3). The quenching medium may also be formed by an inert gas in the liquid state blown onto the product by nozzles. The steel strips obtained are easier to shear and coiled at the output end of the casting line owing to the absence of martensite in the ferritic matrix.
