What Is Inconel 690

Due to its high corrosion resistance to oxidizing acidic media, it can also be used to process nitric acid, nitric acid + hydrofluoric acid and other chemical equipment and components.

The materials for the heat transfer tubes of steam generators in PWR nuclear power plants have gone through a development process, including 304 austenitic stainless steel, 600 alloy, 800 alloy and 690 alloy. Research on corrosion failure of 600 alloy in service shows that intergranular corrosion and intergranular stress corrosion cracking are the main problems. Alloy 690 is used as a heat transfer tube material for steam generators in PWR nuclear power plants. Since it was put into use in the 1990s, no damage has been reported, and the effect is very good.
