Specifications:
Titanium Grade 1 is designated as UNS R50250
Titanium Grade 1 is the softest titanium with the highest ductility, good cold form-ability which gives Titanium Grade 1 an excellent resistance from mild to high oxidation. Commercially Pure Titanium Grade 1 is one of the softest and most ductile grades exhibiting the greatest formability. It has excellent corrosion resistance property, excellent weldability and is used in a wide variety of applications. Titanium Grade 1 is mainly used in marine and chemical industries where the parts are subjected to very harsh environments. Titanium Grade 1 is also used for fabricating anodes for cathodic protection applications.
Applications:
Airframe components, cryogenic vessels,honeycomb, gaskets, heat exchangers, CPI equipment, condenser tubing, pickling baskets, deep drawing applications.
Product Forms of Titanium Grade 1:
seamless pipe, welded pipe, seamless tube, welded tube, bar, wire, sheet, plate, forgings, pipe fittings and flanges.
