ASME SB338 GR1, GR7, GR9, GR12 Titanium Alloy Steel Seamless Tube for Condenser and Boiler Application
ASME SB338 GR7 is a titanium alloy material GR2. Titanium alloy steel has high strength, low density, good mechanical properties, good toughness, and corrosion resistance. In addition, titanium alloy steel materials have poor processing properties and are difficult to cut. In Hot working, it is very easy to absorb impurities such as hydrogen, oxygen, nitrogen and carbon. There is also poor wear resistance and complex production process. The industrial production of titanium began in 1948. The development of the aviation industry requires the titanium industry to grow at an average annual rate of about 8%. The annual production of titanium alloy processing materials in the world has reached over 40000 tons, with nearly 30 titanium alloy grades.
In the mid-1960s, titanium and its alloys were used in general industry, such as making electrodes for electrolysis industry, condensers for power stations, heaters for petroleum refining and seawater desalination, and Waste minimisation devices. Titanium and its alloys have become a corrosion-resistant structural material. In addition, it is also used for the production of hydrogen storage materials and shape memory alloys. The use of titanium alloy material in gr2 is good. Titanium is an important structural metal developed in the 1950s. Titanium alloys have high strength, good corrosion resistance, and high heat resistance.
