  • Patent number: 4938808
    Abstract: Martensitic stainless steel sheet containing (in % by weight) 0.40% or less of C, 1.0% or less of Si, 1.0% or less of Mn, 0.6% or less of Ni, 10-14% of Cr. 0.025-0.30% of Al, and 0.025-0.060% of N, with the balance being iron and incidental impurities, has improved oxidation resistance, workability, and corrosion resistance. This type of stainless steel sheet is produced by a series of steps of hot rolling steel material of the above composition into a hot-rolled steel sheet, then softening by heating at a temperature in the range of 650.degree.-900.degree. C. for a short time within 300 seconds, and thereafter conducting pickling, cold rolling, and finish annealing. Moreover, in the above martensitic stainless steel sheet and the method of producing the same, it is desirable to set the Al content at 0.05-0.20% and/or the N content at 0.03-0.05%.
