Commercially Pure Grade 2 Titanium is one of the most common grades of unalloyed titanium. It has good corrosion resistance and formability due to controlled chemistry and is stronger than CP Grade 1 but weaker than higher grades. CP Grade 2 titanium is used in chemical, marine, medical, recreational and aerospace industries and is available as rod, plate or sheet to specifications like ASTM B348 Grade 2. It has defined maximum compositions of alloying elements and minimum tensile properties.

1. Commercially Pure Grade 2 Titanium
Alternate Names:CP Grade 2 Titanium, CP2, Grade 2, CP 40
Description: 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 Grade 2 Titanium is available in the following ProductForms:
Round Bar (Rod), Plate, and Sheet
