INTRODUCTION TO THE
690 alloy has excellent resistance to intergranular corrosion and intergranular stress corrosion cracking. It is mainly used as the material of steam generator heat transfer tube in pressurized water reactor nuclear power plant. The materials for steam generator heat transfer tube of PWR nuclear power plant have gone through a development process, including 304 austenitic stainless steel, 600 alloy, 800 alloy and 690 alloy. The corrosion failure of 600 alloy in service shows that intergranular corrosion and intergranular stress corrosion cracking are the main problems. Alloy 690, as a material of steam generator heat transfer tube in pressurized water reactor nuclear power plant, has not been damaged since it was put into use in 1990s.
