Abstract
The drawability of 18Cr stainless steel sheets is strongly affected by the crystallographic orientation and not by the grain size. The drawability of 18Cr stainless steel sheets produced by a single cold rolling and annealing process is very poor, because a considerable amount of the {100} component parallel to the sheet plane, which is mainly composed of {100}〈011〉 inherited from the hot rolled condition, is retained and the increase of the {111} component can hardly be anticipated in the process.In general, 18Cr stainless steel thin sheets are produced by a double cold rolling and annealing process. It is well known that the drawability of mild steel sheets of greatly improved drawability can be processed in the “double” process. So it has been tried to improve the drawability of 18Cr stainless steel sheets by the application of the “double” process.Consequently, it is found that the drawability of 18Cr stainless steel sheets is greatly improved by a proper combination of cold rolling reduction in each stage.
