Abstract
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, produced in slab form, containing in its composition by weight: 18% < chromium < 27%; 1% < molybdenum < 3%; 1% < nickel < 3%; manganese < 1%; silicon < 1%; carbon < 0.030%; nitrogen < 0.030%; 0.075% < titanium < 0.20%; 0.20% < niobium < 0.50%; sulphur < 0.01%; phosphorus < 0.1%, the balance being iron and impurities resulting from the smelting of the materials necessary for the production, is subjected, in a first phase, to cooling at a rate of between 400 DEG C and 600 DEG C/hour down to a temperature of 900 DEG C and then, in a second phase, to rapid cooling at a rate of between 1200 DEG C and 1400 DEG C/h.
