Yunus Sheets and Plates is a renowned Istanbul, Turkey-based manufacturer and supplier that provides high-quality Inconel 690 circles known for superior corrosion resistance and high-temperature strength. With state-of-the-art alloying and high-tech manufacturing techniques, our Inconel 690 circles are in line with global standards and engineered to perform in demanding applications for power generation, chemical processes, and nuclear fields. With rigorous quality control and sophisticated production facilities, Yunus Sheets and Plates provides trustworthy and long-lasting Inconel 690 circles for critical components where they are subjected to harsh environments.
Inconel 690 rings are nickel-chromium alloys that comprise about 58% nickel and 27-31% chromium, along with minor percentages of iron, manganese, and silicon. The alloying elements in this composition confer high resistance to oxidation, carburization, and stress corrosion cracking, particularly in high-temperature and aggressive chemical conditions. The alloy also provides favorable mechanical strength and excellent weldability, making it an appropriate alloy for fabrication of intricate components that need durability and reliability at the levels of thermal and chemical stresses.
