TIMET TIMETAL® 50A CP Titanium (ASTM Grade 2)
Categories: Metal; Nonferrous Metal; Titanium Alloy; Unalloyed/Modified Titanium

Material Notes: Commercially Pure Titanium.

Industry Specifications: USA Aerospace: AMS 4902, 4941. Germany Engineering: 3.7035. Germany Aerospace: 3.7034. France: T-40. UK Aerospace Specifications BS TA. 2, 3, 4, 5.

Features: The mechanical properties of CP titanium are influenced by small additions of oxygen and iron. By careful control of these additions, the various grades of commercially pure titanium are produced to give properties suited to different applications. TIMETAL 50A is equivalent to ASTM Grade 2. It is the "workhorse" for industrial applications, having a guaranteed minimum 0.2% yield strength and good ductility and formability. It is used extensively for sea water piping, reactor vessels and heat exchangers throughout the CPI, Petrochemical, Oil and Gas and Naval/Marine markets. This alloy is also ASME approved, has good impact properties at low temperatures, and has excellent resistance to erosion and corrosion by seawater and marine atmospheres. It can be easily welded, machined, cold worked, hot worked, and cast. It is nonmagnetic.

Typical heat treatment for this alloy: Anneal at 700°C for 1 hour and air cool. Stress Relieve at 500°C for 30 mins and air cool.
