Commercially Pure Grade 2 Titanium is one of the most common grades of unalloyed Titanium. In Commercially Pure Titanium, the mechanical properties are controlled by the chemistry input; higher amounts of Nitrogen, Oxygen, and Iron will increase strength properties. CP Grade 2 is higher in strength than CP Grade 1, but lower in strength than CP Grade 3 and CP Grade 4.
It is sometimes referred to as “CP 40” due to its approximate yield strength. CP Grade 2 Titanium typically comes in the annealed condition. It is an attractive Grade of Titanium due to its excellent corrosion resistance, good formability, and limited strength. It is used in a variety of industries such as chemical, marine, medical, recreational, and aerospace. Machinability: Low cutting speeds, heavy feed rates, sharp tools, and ample cutting fluid are prescribed.

CP Ti Grade 2 is highly resistant to many chemical environments including oxidizing media, alkaline media, organic compounds and acids, aqueous salt solutions, and wet or dry hot gases. It also has sufficient corrosion resistance in liquid metals, nitric acid, mildly reducing acids, and wet chlorine or bromine gas (as long as a minimal amount of oxygen or water is present).
