Grade 4
EN/DIN
EN 10204/3.1B
Commercially pure or CP, non-titanium alloy. Consists of 100% hcp alpha phase at service temperatures. As a single-phase material, its properties are controlled by chemistry (iron and interstitial impurities) and grain size. CP Titanium is classified from Grade 1 to Grade 4 depending on the strength and allowable levels of iron, carbon, nitrogen and oxygen elements. CP Ti Grade 4 is the strongest of these classes with a minimum yield strength of 480 MPa (70 ksi) and has the highest permissible oxygen and iron content of the classes.
Grade 4 combines titanium's excellent resistance to corrosion and corrosion fatigue with high strength, making it a candidate to compete with steels and nickel alloys for many chemical and marine applications.

Physical Properties
Unalloyed and considered commercially pure or "CP". In general, the tensile strength and yield strength increase with the figure of merit for these "pure" qualities. The difference in their physical properties is mainly due to the amount of intermediate elements. They are used for corrosion resistance applications where cost, ease of manufacture and welding are important.
