CP Grade 3

Common Name
CP Grade 3
Titanium Grade 3
UNS
R50550
General Information
Titanium Alloy Grade 3 is “unalloyed” titanium offering improved strength, moderate ductility, and ASME Code design allowables. The material is readily weldable. This material is very corrosion resistant in highly oxidizing and mildly reducing environments. The material is castable and is often utilized in cast valves and fittings. The alloy is available as castings, wire, welded tube, pipe, plate, sheet, strip, forgings, bar, and billet.
