Abstract:The effect of the cold rolling process on the wrinkle resistance of 443 ferrite stainless steel surface was studied. The results showed that the surface anti-wrinkle property can be improved obviously by the second rolling process. After the first rolling process, there were grain clusters in the center of rolling plate, which were distributed in strips along the rolling direction, and the grain size was non-equiaxed crystals with large sizes. The core structure of the cold-rolled plate in the second rolling pass was uniform. For the first rolling pass, in addition to the γ-fiber recrystallization, the surface and core of the cold-rolled plate retained a strong {112}<110> texture, and the strength of the γ-fiber recrystallization texture was less than that for the second rolling process. It could effectively eliminate the adverse effects of the original columnar solidification structure, weaken the deformation texture of α-fibers, and make the microstructure grain orientation distribution more uniform by adopting the second rolling process.
