摘要： A method for producing bright stainless steel whereby a hot mill band having a dull oxide-free surface is first formed. The hot mill band is cold reduced to form a full hard coil having a shiny surface. The coil is subjected to continuous annealing at a temperature of 1500.degree.-1950.degree. F. in an oxygen-containing atmosphere sufficient to form a protective FeCr.sub.2 O.sub.3 scale. The annealed coil is subjected to a mild non-etching pickling process to remove the black scale. The coil is then rolled on a temper mill having specially finished rolls to impart a surface pattern that replicates an abrasively polished surface.

摘要： A continuous process line for converting hot rolled stainless steel strip to final gauge product is provided. The stainless steel strip has a scale formed on the surface thereof. The steel strip is introduced to a rolling mill to reduce the thickness of the hot rolled stainless steel to a final gauge thickness and tolerance. The rolling mill also cracks the scale on the surface of the final gauge thickness strip. An annealing section anneals the final gauge thickness strip received from the rolling mill. A pickling section pickles the annealed strip from the annealing section and removes the scale from the surface. Preferably, a molten salt bath section provided between the annealing section and the pickling section conditions the scale cracked in the cold rolling section and passes the conditioned stainless steel to the pickling section.
