Abstract
Effect of roll diameter in cold rolling on r-value and specular glossiness on 17%Cr stainless steel sheet has been investigated.
It was found that r-value increased with increasing roll diameter in the cold rolling and the specular glossiness increased when cold rolled with small diameter roll in the later part of cold rolling.
Combination of large diameter roll in the former stage of cold rolling and small diameter in the later stage of cold rolling gave better r-value and higher specular glossiness than cold rolled only by small or large diameter roll.
