PROCESS FOR MANUFACTURING FERRITIC STAINLESS STEEL SHEET HAVING GOOD FORMABILITY, SURFACE APPEARANCE AND CORROSION RESISTANCE

摘要

A ferritic stainless steel containing 12.00 25.00% of Cr, 0.1 - 2.0% of Cu and 0.2 - 2.0% of Nb with sulfur being restricted to not greater than 0.02%, preferably not greater than 0.005% is hot rolled with a finishing temperature of 850.degree.C or less, which is lower than the usual finishing temperature, and the resulting hot rolled steel strip is annealed at a relatively high temperature of 950 1050.degree.C. The resulting cold rolled steel sheet, though it is less expensive, possesses good formability, ridging resistance, surface appearance and corrosion resistance, and is particularly suitable for making ornamental articles, such as automotive mouldings.
