High Quality 
Mature Technical 
Safe and 
303 stainless steel cold drawn round bar is an excellent candidate for most processing techniques as well as both indoor and outdoor applications. This product, designed for close tolerances, has a semi-smooth, dull grey finish with accurate dimensions throughout length. 303 stainless steel is a high strength material with excellent corrosion resistance making it ideal for shafts, hinges, dowels and other structural applications. ASTM A314 is the standard specification for stainless steel billets and bars for forging.
