Abstract

PURPOSE:To obtain an austenitic stainless steel sheet having low anisotropy in the surface by specifying the hot rough rolling condition of a steel slab, descaling after finishing rolling, cold rolling in two steps then annealing finally said material. CONSTITUTION:The slab of austenitic stainless steel is heated to 1,200-1,300 deg.C, and hot rolled. Thereat, said slab is roughly rolled by one pass or more under >=25%/pass reduction ratio, hot rolled with finishing at >=1,050 deg.C, then said material is wound at <=650 deg.C. Next, descaling is performed without annealing the hot rolled plate. Successively, said plate is cold rolled by >=30% cumulative reduction ratio by using large diameter working roll having >=200mm. diameter. Next, cold rolling is performed by >=30% reduction by using small diameter working roll having <200mm. diameter. Thereafter, final annealing and skin pass rolling are performed to obtain the steel sheet or strip being the final product.
