Inconel 690 superheater tube is an alloy mainly used for heat transfer tube materials of steam generators in pressurized water reactor nuclear power plants, and is the core technology of steam generators.
Alloy 690 nickel-based alloy tube has excellent resistance to intergranular corrosion and intergranular stress corrosion cracking, and is mainly used for heat transfer tube materials of steam generators in pressurized water reactor nuclear power plants.
The materials for heat transfer tubes of steam generators in pressurized water reactor nuclear power plants have gone through a development process, including 304 austenitic stainless steel, 600 alloy, 800 alloy and 690 alloy. Intergranular corrosion and intergranular stress corrosion cracking are the main problems. As a heat transfer tube material for steam generators in pressurized water reactor nuclear power plants, 690 alloy has never been damaged.
