Material Notes:
Description: 304Cu UGIMA® is an enhanced machining grade produced only by Ugitech, providing the ultimate level of machinability available in an non-resulfurized austenitic stainless steel. 304Cu UGIMA® also features the added benefit of increased cold formability when compared with that of standard type 304 stainless steels. The increased copper content in 304Cu UGIMA® provides corrosion resistance superior to 304L and comparable to 316L. The unique combination of machinability, cold formability, and corrosion resistance afforded by 304Cu UGIMA® is unique in the industry, and provides the optimum solution for even the most difficult fabrication challenges. 304Cu UGIMA® builds upon the proprietary UGIMA manufacturing process with the addition of copper, allowing for good machinability across a wide range of operations and cutting conditions. It allows for superior machinabilty at both low and high speeds, cam-driven and CNC machines, and with high-speed steel or carbide tooling. Machine shops using 304Cu UGIMA® have experienced consistent success regardless of machine, operation, tooling, or cutting conditions. From lot to lot 304Cu UGIMA® is engineered to give the same high performance every time without surprises.Information provided by Schmolz + Bickenbach
