Inconel 690

Inconel is a high chromium nickel-based superalloy with excellent water corrosion resistance and stress cracking resistance. The chromium content is about 30%, which is significantly higher than the chromium content in other alloys. Therefore, it has excellent resistance to thermal oxidation gases and oxidizing chemicals. High resistance, and has a certain resistance to vulcanization at high temperature.Alloy 690 can be available in Bar, Pipe, Forging, Plate, Fasteners, Coil, Wire, Fitting, etc.

Overview of Inconel 690

Other common names: Alloy 690, UNS N06690, W. Nr. 2.4642

Inconel 690 is a high-chromium nickel-based superalloy with excellent water corrosion resistance and stress cracking resistance. The chromium content is about 30%, which is significantly higher than the chromium content in other alloys. Therefore, it is resistant to high-temperature oxidizing gases and oxidizing chemicals. High resistance, and a certain degree of resistance to sulfidation at high temperatures, high nickel content endows the alloy with resistance to stress corrosion cracking in chloride environments and sodium hydroxide solutions. In addition to corrosion resistance.Allloy 690 also has high strength, good metallurgical stability and workability, and is mainly used in heat transfer tubes for steam generators in water reactors (PWR) nuclear power plants.

Features of Inconel 690

● Excellent resistance to intergranular corrosion and stress corrosion cracking

● Good resistance to stress corrosion cracking caused by alkali

● Excellent resistance to many corrosive water media or primary and secondary circuits of nuclear reactors

● Good anti-oxidation, anti-sulfur and anti-high temperature gas properties

● Good mechanical properties at room temperature and high temperature, good ductility and weldability
