Titanium Grade 3, Sheet & Coil, AMS 4900 (CP Grade 3) - UNS R50550
Commercially Pure or CP Titanium in unalloyed. Grade 3 is a general purpose grade of commercially pure titanium that has excellent corrosion resistance in highly oxidizing to mildly reducing environments, including chlorides, and an excellent strength to weight ratio. Grade 3 titanium features the highest ASME allowable design stresses of any commercially pure grade of titanium. It has good impact properties at low temperatures. It can be welded, machined, cold worked, hot worked, and cast.
