Product Description
303 stainless steel round bar has a lower corrosion resistance, formability and weldability than 304. However, it has optimum machinability among the stainless steels. It should not be exposed to marine environments, because this will result in rapid pitting and corrosion. Uses include nuts, bolts and aircraft fittings/gears.
