Titanium Grade 7 Pipe
Products Description
ASTM Grade 7, UNS R52400, CP titanium, C.P. titanium alloy
Introduction
Titanium alloys have several advantageous attributes that allow their use in industries like automobiles, consumer electronics, military, aerospace, medical, marine, and sports equipment.
Grade 7 Ti-0.15Pd alloy is highly resistant to corrosion in reducing acids and localized attack in hot halide media. The presence of palladium helps to enhance the alloy's corrosion resistance. This alloy is similar to grade 2 and possesses medium strength and ductility.
The following sections will discuss in detail grade 7 Ti-0.15Pd alloy.

|---|---|---|
| Thermal conductivity (room temperature) | 20.8 W/mK | 144 BTU in/hr.ft².°F |
Welding
Weldability of grade 7 Ti-0.15Pd alloy is rated as excellent. This alloy is a single-phase material, hence the microstructure of the alpha phase is not affected by thermal treatments or welding temperatures.
Annealing
Annealing of this material can be performed by heating to 650-760°C (1202-1400°F) for 6 min -2 h and then air-cooled. In case stress relieving is required, the material has to be heated to 480-595°C (896-1103°F) for 15 min - 4 h, and then air-cooled.
Applications
Grade 7 Ti-0.15Pd alloy is used in the following application areas:
Anode/cathode/cell components
Chemical processing equipment
Air pollution control equipment
Pulp/paper bleaching/washing equipment
Hydrometallurgical extraction/electrowinning
Desalination, brine concentration/evaporation
