Inconel Alloy 690 (UNS N06690) – Composition, Properties and Uses
Inconel Alloy 690 (UNS N06690) – 1. Composition:
Inconel 690 alloy is a nickel-based high-temperature alloy whose composition has been carefully designed and optimized to give the alloy outstanding properties. The main components of the alloy include nickel (Ni), chromium (Cr), and iron (Fe), of which nickel is the matrix element and occupies the majority of the alloy. In addition, a small amount of strengthening elements such as carbon (C), molybdenum (Mo), and cobalt (Co) are added to the alloy to improve its mechanical properties and corrosion resistance.
The combination and proportion of these elements are carefully formulated to ensure that Inconel 690 alloy maintains stable performance in high temperatures and harsh environments. Specifically, the high content of nickel makes the alloy ductile and tough, while the addition of chromium and iron enhances the alloy’s corrosion resistance and strength. At the same time, the addition of strengthening elements such as carbon, molybdenum, and cobalt further improves the strength and hardness of the alloy.
Inconel Alloy 690 (UNS N06690) – 2. Properties:
Inconel Alloy 690 has a range of outstanding properties that make it suitable for a wide range of applications in various fields.
- Corrosion resistance: The alloy shows good resistance to a variety of corrosive media, including oxidizing media, reducing media, and high-temperature water vapor.
