Method of working a hot-rolled strip |
摘要 |
The invention relates to a method of working a hot-rolled stainless steel strip, particularly an austenitic stainless strip, with the intention of reducing the thickness and enhancing the mechanical strength of the strip. The method is characterized by cold-rolling the hot-rolled strip with at least a 10% thickness reduction to a thickness which is at least 2% and at most 10% greater than the intended final thickness of the finished product; annealing the thus cold-rolled strip at a temperature of between 1,050 DEG C. and 1,250 DEG C.; and cold-stretching the strip after the annealing process so as to plasticize and permanently elongate the strip and therewith reducing its thickness by 2-10%.
