Material Notes:
Description: CLI - SAF 2507® is a 25.07 super duplex stainless steel with 25% Cr and a PREN value higher than 40. The minimum guaranteed yield strength is 550 MPa which allows the designer to reduce weight. The molybdenum and nitrogen additions have been optimized in order to obtain the best corrosion resistance properties even for heavy plates. Its high nitrogen content improves the structure stability particularly in HAZ. The CLI - SAF 2507® (URANUS® 47N+) grade is an overalloyed variant of the former UR 47N grade of CLI. CLI - SAF 2507® has improved corrosion resistance properties when compared to duplex 2205 type materials, or even to URANUS® 47N. It is designed for service in severe corrosive conditions. The alloy is particularly resistant to stress corrosion cracking and crevice corrosion. CLI - SAF 2507® is a cost efficient grade designed for Oil & Gas industry, Seawater applications, Desalination plants, Geothermal wells or Refineries and Petrochemical plants.Information provided by manufacturer.
