We are into the business of manufacturing, exporting, trading and supplying a wide range of Stainless Steel 303 Round Bar. Our bars are widely appreciated by the customers for their optimum quality, durability and many other features. Our range is made using supreme grade raw material that makes them durable. We have reasonably priced our range. 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. 303 UNS 30300 stainless steel bars were developed for machining. Type 303 has a higher concentration of sulfur reducing the drag on cutting tools. It allows greater machining speeds and lower production costs. The alloy is useful whenever a need arises for good corrosion resistance and considerable machining is required.
