Process for the production of stainless steel sheets having an excellent corrosion resistance

Abstract

This invention relates to a process for the production of stainless steel sheets and proposes a process for the production of stainless steel sheets having a more excellent corrosion resistance as compared with the conventional one without trimming the steel sheet surface after annealing-pickling by preventing the chapping of steel sheet surface created in the production of present stainless steel sheet, particularly stainless steel sheets having extreme-low amounts of C, S, O. For this purpose, according to the invention, a starting material of stainless steel containing C: not more than 0.01 wt %, S: not more than 0.005 wt % and O: not more than 0.005 wt % is subjected to a hot rolling at a draft below 830.degree. C. of not less than 30%, cooled at a cooling rate of not less than 25.degree. C. sec, coiled below 650.degree. C. and then annealed and pickled.
