AISI 304 quality stainless steel is an indispensable material for daily use thanks to its high corrosion resistance, high thermal conductivity, formability and visual properties. Especially in the kitchen, petrochemical, marine industry and in the manufacture of medical equipment, stainless steels are frequently used. Stainless steel flat materials are produced by hot rolling, annealing and cold rolling after casting, and are then prepared for service lines by annealing and surface passivation [1].
