Application areas | Sanicro® 69 is used in: | |
Certifications | Approvals: | |
Cold Forming | The excellent formability of Sanicro® 69 permits cold-bending to very small bending radii. Annealing is normally not necessary after cold-bending owing to the high stress corrosion cracking resistance for Sanicro® 69. | |
Corrosion properties | Stress corrosion cracking: The thermally treated condition of Sanicro® 69 is developed specifically to resist stress corrosion cracking in steam generator environment at nuclear power plants. This has been confirmed by laboratory stress corrosion cracking tests in pure water (less than 5 ppm oxygen, 4-5 ppm hydrogen added) at 365°C (690°F). No stress corrosion cracking was developed in Sanicro® 69 during the entire test period of 33 000 hours. Alloy 600 started to crack after 200 hours. Intergranular corrosion: Sanicro® 69 has good resistance to intergranular corrosion in both the thermally treated condition and the solution annealed condition. Typical corrosion rates in the Huey test (65% HNO₃, 5 x 48h, ASTM A262 Practice C) are 0.06 mm/year (2.4 mpy). The figure on the right side shows a TTS diagram for a heat of Sanicro® 69 with 0.03% carbon tested in the Huey test. The initial material was annealed at 1040°C (1900°F), 20 min/WQ. As can be seen there is a very narrow area where Sanicro® 69 shows some tendency for sensitization. General corrosion: Sanicro® 69 and Alloy C-276 have been corrosion tested in 20% HNO₃+ 4%HF at 65°C (150°F). Sanicro® 69 had a corrosion rate of 0.625 mm/year (24.6 mpy) while Alloy C-276 suffered a corrosion rate of 23.7 mm/year (933 mpy). | |
Expanding | Sanicro® 69 is expanded into tube sheets in the same way as standard austenitic stainless steels. | |
Heat Treatment | For steam generator application the tubes are delivered in the thermally treated conditions. This means exposure at about 720°C (1330°F) for normally 10 hours. Prior to the thermal treatment the tubes are solution annealed at approximately 1100 °C (2010°F) for some minutes. For other applications the tubes are delivered in the solution annealed condition. If additional solution annealing is necessary after further processing the following procedure is recommended: 1050-1150°C (1920-2100°F), 1-10 minutes, rapid cooling in air or water. | |
Other | Forms of supply: Seamless tube and pipe are supplied in the size range from 1/4" O.D. (6.35 mm) to 4" O.D. (101.6 mm) in wall thickness from 0.030" (0.9 mm) to 1" (25.4 mm). Tube and pipe are delivered in the solution annealed and pickled condition. PWR steam generator tubes are delivered in the bright annealed and thermally treated condition. The thermal treatment involves a treatment in vacuum furnace at about 720°C (1330°F) for normally 10 hours. | |
Welding | The weldability of Sanicro® 69 is good. Suitable methods of fusion welding are manual metal-arc welding (MMA/SMAW) and gas-shielded arc welding, with the TIG/GTAW method as first choice. For Sanicro® 69, heat-input of <1.0 kJ/mm and interpass temperature of <100°C (210°F) are recommended. A string bead welding technique should be used. Recommended filler metals:
