Study on direct cold rolling of hot rolled austenitic stainless steel SUS 304 with oxide scale

The austenitic stainless steel SUS 304 with oxide scale was directly cold rolled at different reductions of 10%, 20% and 30% respectively.It was proved that the surface quality(lower surface roughness)of the cold rolled products was achieved after subsequent annealing and pickling possesses,compared to the conventional hot rolled No.1 product, whereas the grain size,mechanical and corrosion-resistant properties were comparable to those of the No.1 product.
