AWS A5.16 ERTi-3


CP-3 Titanium

CP-3 Titanium is a higher strength unalloyed (or Commercially Pure–CP) grade. Grade 3 is used for process equipment, tubing and pipe. Grade 3 is not as readily available as CP-2, but should be considered in applications where its higher strength reduces metal thickness required, and where the quantity of metal justifies a mill purchase.
