Frequently Asked Questions
1. What is Inconel 690 (UNS N06690) Round Bar used for?
Inconel 690 Round Bar is used to manufacture steam generator tubes, heat exchangers, furnace components, and equipment for nuclear, chemical, and power generation industries.
2. Why is Inconel 690 preferred for nuclear steam generator applications?
Inconel 690 is preferred because it offers excellent resistance to stress corrosion cracking, high-temperature oxidation, and corrosion in high-purity water and steam environments.
3. What is the difference between Inconel 690 and Inconel 600?
Inconel 690 contains a higher chromium content (27–31%) than Inconel 600, giving it significantly better resistance to oxidation and stress corrosion cracking.
4. Does Inconel 690 contain cobalt or molybdenum?
No. Standard Inconel 690 does not contain significant amounts of cobalt or molybdenum. Its excellent corrosion resistance comes primarily from its high nickel and chromium content.
5. Is Inconel 690 resistant to stress corrosion cracking and high-temperature oxidation?
Yes. Inconel 690 provides outstanding resistance to stress corrosion cracking, oxidation, and high-temperature corrosion, making it suitable for severe industrial environments.
