Corrosion Stainless Steel

DUPLEX STAINLESS STEEL GRADE

SD 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 SD 2507 (UR 47N ) grade is an overalloyed variant of the former UR 47N
grade of Duplex Series..

SD 2507 has improved corrosion resistance properties when compared to duplex
2205 type materials, or even to UR 47N. It is designed for service in severe
corrosive conditions.

The alloy is particularly resistant to stress corrosion cracking and crevice
corrosion.
SD 2507 is a cost efficient grade designed for Oil & Gas industry, Seawater
applications, Desalination plants, Geothermal wells or Refineries and
Petrochemical plants.
