Schmolz + Bickenbach UGIMA® 630 Stainless Steel Bar
Categories:	Metal; Ferrous Metal; Stainless Steel; Precipitation Hardening Stainless; T 600 Series Stainless Steel
Material Notes:	630 UGIMA® is an improved machining martensitic precipitation hardenable grade. It is identical to standard type 630 (17-4), except with respect to machinability. The proprietary UGIMA® manufacturing process – developed by Ugitech – results in a product that increases productivity and tool life, and improves the surface finish on all types of machined parts. 630 UGIMA® provides a good combination of high strength corrosion resistance, and is often the best solution of stainless steel when high strength is required. Parts machined from solution treated bar stock should be heat treated or aged prior to use. No further heat treatment of machined parts is required when using 630 UGIMA® is one of the precipitation hardened conditions as specified. Applications: Fasteners, Shafts, Valve Bodies, Valves, Valve Trim, Fitting, Machined parts, Medical devices, Aircraft components, and Not recommended for vessels containing liquid or gasses at high pressure Information provided by Schmolz + Bickenbach
