Inconel 690 738 Steel Pipe
690 Alloy Pipe Inconel 690 Pipe (UNS N06690) is a high chromium nickel-based alloy that offers excellent resistance to corrosion in a wide range of aqueous media and high temperature atmospheres. It also offers high strength, good metallurgical stability, and excellent processing characteristics.
Inconel 738 tube is a tube made of nickel-based high-temperature alloy, the main components of which are nickel (balance), chromium (15.7-16.3%), cobalt (8.0-9.0%), molybdenum (1.5-2.0%), aluminum (3.4-3.8%), titanium (3.2-3.7%) and a small amount of niobium. The alloy has extremely high high-temperature strength, oxidation resistance and corrosion resistance, and can maintain stable performance under extremely high temperature and high reliability environments. Therefore, it is widely used in gas turbines, aircraft engines, industrial heating equipment, and petrochemical industries. 738 tube is particularly suitable for the manufacture of high-temperature components such as combustion chambers, turbine blades and Bluetooth, and is a material for inflating in high-temperature industrial applications.
