Stainless Steel Wire 303Cu

303Cu stainless steel wire or 1.4570 is a free-machining austenitic stainless steel much like 303 but with added copper content. The copper content is increased for 1.00 to 1.40-1.80 which gives this material outstanding machinability. The increase also supports improved corrosion reistance in acidic environments. We have extensive knowledge on packaging the material especially suited to free machining.
