303 stainless steel bar
7/16" (.437) Square rod 12" long  

303 stainless steel is an "18-8" chromium-nickel stainless grade with sulfur added to make it a free machining grade. The most easily machined stainless grade has good atmospheric corrosion resistance and is a good choice for screw machines. It is non-magnetic in the annealed condition and non-hardenable by heat treating. Typical applications include: nuts, bolts, shafts, bushings, screws, parts requiring machining, grinding or polishing.
