Material Notes:
Description: 303 UGIMA UX® is an improved machining grade produced only by Ugitech, providing the ultimate level of machinability available in an austenitic stainless steel. 303 UGIMA UX® features the added benefit of increased cold formability when compared with that of standard type 303 stainless steels. The combination of machinability and cold formability affored by 303 UGIMA UX® is great, and provides the optimum solution for even the most difficult fabrication challenges. Other advantages offered by 303 UGIMA UX® when compared with standard type 303 stainless steels include increased corrosion resistance in certain media, and ability to withstand moderate amounts of cold deformation with no significant increase in magnetic permeability. 303 UGIMA UX® builds upon the proprietary UGIMA® technology with the addition of copper, allowing for good machinablity across a wide range of operations and cutting conditions. It allows for machinability at both low and high speeds, in cam-driven and CNC machines, and with high-speed Steel or carbide tooling. Machine shops using 303 UGIMA UX® have experienced consistent success regardless of machine, operation, tooling, or cutting conditions. From lot to lot, 303 Ugima UX® is engineered to give the same high performance every time without surprises.Information provided by Schmolz + Bickenbach
