About Grade 3|Commercially pure titanium with higher oxygen content than
Grade 2, giving about 15% more strength (65 KSI yield vs 50 KSI). Same corrosion resistance and weldability as Grade 2. Used when CP titanium's strength isn't quite enough but you don't need the jump to
Grade 5. Less commonly stocked than Grade 2. Machines similarly to Grade 2. Compare to Grade 2 (more common, slightly lower strength) and
Grade 4 (even stronger CP titanium).
