Alloy 690 has excellent resistance to intergranular corrosion and intergranular stress corrosion cracking, and is mainly used as a heat transfer tube material for steam generators in pressurized water reactor nuclear power plants. The material of the steam generator heat transfer tube of the pressurized water reactor nuclear power plant has undergone a development process, including 304 austenitic stainless steel, 600 alloy, 800 alloy and 690 alloy. In-service corrosion failures of Alloy 600 show that intergranular corrosion and intergranular stress corrosion cracking are the main problems. Alloy 690 as Heat Transfer Tube Material of Steam Generator in Pressurized Water Reactor Nuclear Power Plant. Inconel 690 is a high-temperature alloy, also known as UNS N06690. Some international standards and specifications for Inconel 690 include: American standards: ASTM B166, ASTM B564, ASTM B167, ASTM B829, ASTM B517, ASTM B775, ASTM B163, ASTM B514, ASTM B751, ASTM B670, ASTM B366, ASME SB-166, ASME SB-564, ASME SB-167, ASME SB-829, ASME SB-517, ASME SB-775, ASME SB-163, ASME SB-514, ASME SB-751, ASME SB-670, ASME SB-366 European standards: EN 2.4642, EN 2.4641, EN 2.4856, EN 2.4858, EN 2.4859, EN 10216-2, EN 10217-2, EN 10216-5, EN 10217-5, EN 10088-1, EN 10095, EN 10222-2, EN 10269, EN 10272, EN 10297-2, EN 10302, EN 10312 Japanese standards: JIS G4801, JIS G4804, JIS G4805, JIS G4802, JIS G4311, JIS G4312, JIS G4313, JIS G4321, JIS G4322, JIS G4323, JIS G4308, JIS G4318, JIS G5121, JIS G5151, JIS G5152, JIS G5501, JIS G5502, JIS G3446 Chinese standards: GB/T 14992, GB/T 14994, GB/T 15001, GB/T 15003, GB/T 15007, GB/T 15009, GB/T 15011, GB/T 15013, GB/T 15014, GB/T 15021, GB/T 15023, GB/T 15025, GB/T 15027, GB/T 15029, GB/T 15031, GB/T 15033, GB/T 15037, GB/T 15039, GB/T 15041, GB/T 15043, GB/T 15045, GB/T 15047, GB/T 15049, GB/T 15051, GB/T 15053, GB/T 15055, GB/T 15057, GB/T 15059, GB/T 15061, GB/T 15063, GB/T 15065, GB/T 15067, GB/T 15069, GB/T 15071, GB/T 15073, GB/T 15075, GB/T 15077, GB/T 15079, GB/T 15081, GB/T 15083, GB/T 15085, GB/T 15087, GB/T 15089, GB/T 15091, GB/T 15093, GB/T 15095, GB/T 15097, GB/T 15099, GB/T 15101, GB/T 15103, GB/T 15105, GB/T 15107, GB/T 15109, GB/T 15111, GB/T 15113, GB/T 15115, GB/T 15117, GB/T 15119, GB/T 15121.
