Products Description
Grade 7 titanium tubing (3.7235, R52400) is known for its high quality, strength, durability, thin thickness, and resistance to high and low temperatures. Grade 7 titanium alloy seamless tubing, with its chemical name Ti, is also known as Ti Gr2 tubing. ASTM B778 titanium alloy Grade 7 seamless tubing is a lightweight, scratch-resistant, and unattractive metal that outperforms hardened steel in thickness and corrosion resistance, especially in saltwater environments. These Grade 7 titanium welded tubing are also used as Grade 7 titanium alloy heat exchanger tubing in power plants. Grade 7 titanium alloy tubing has a higher specific gravity and a melting point of 1725 degrees Celsius, making ASTM B778 titanium alloy Grade 7 welded tubing useful in steam turbine applications.
