摘要： A process in which a cast strip of Cr-Ni type stainless steel having a thickness close to a product thickness is prepared by the synchronous continuous casting. By subjecting the cast strip just below the casting machine to rapid cooling in the high-temperature region, hot-working or cold-working the cast strip and subjecting the cast strip to annealing or the like, .gamma. grains in the cast strip are made finer, and by carrying out cooling in the low-temperature region of temperatures lower than 900.degree. C., precipitation of Cr carbide in the grain boundary is prevented. Thus, occurrence of roping or uneven gloss on the surface of the stainless steel sheet is controlled.

摘要： A process for producing a cold-rolled strip or sheet of an austenitic stainless steel, comprising the steps of: casting a melt of an austenitic stainless steel into a cast strip in the form of a thin strip having a thickness of 10 mm or less by using a continuous caster in which a casting-mold wall is moved synchronously with the cast strip; cold-rolling the cast strip to form a cold-rolled strip; final annealing the cold-rolled strip; and skin-pass-rolling the annealed strip at an elongation of from 0.5 to 2.5%.
