Inconel 690/UNS N06690/W.Nr. 2.4642
‌Inconel series alloys ‌ belong to the austenitic nickel-chromium base superalloy series, widely used in a variety of extreme environments. Due to its excellent corrosion resistance, high temperature strength and mechanical properties, Inconel alloy has a wide range of applications in aerospace, petrochemical, power generation and other fields.
The main components of Inconel alloys include nickel, chromium, iron, and sometimes other elements such as aluminum, titanium, or molybdenum. These elements give Inconel alloys excellent strength and oxidation resistance at high temperatures. For example, Inconel 600 alloy has good thermal strength and high plasticity below 700 ° C, while having good high-temperature corrosion resistance and oxidation resistance ‌.
