Ti Grade7, its mechanical and physical properties are similar to Gr 2. This grade also has excellent manufacturing, welding and forming properties. In addition, due to the addition of palladium, this grade has strong resistance to acid corrosion and oxidation. Due to its excellent characteristics and mechanical properties, this grade is used in various industries.
This grade is suitable for all types of commercial and industrial applications used at high temperatures. ASTM B338 grade 7 titanium alloy tube is a lightweight, scratch-safe and unattractive metal, superior to hardened steel in thicknessanderosion resistance (especially in salt water). These grade 7 titanium welded tubes are also used as grade 7 titanium heat exchange tubes in power plants. Titanium alloy grade 7 pipes have a high specific gravity with a liquefaction point of 1725'C, which allows the use of ASTM B778 titanium grade 7 welded pipes in the development of flow motors.
