Grade 2507 is one of a group of "super duplex" grades, combining high strength with exceptional corrosion resistance. 2507 is very highly resistant to general corrosion and to pitting and crevice corrosion in high chloride, hot environments. Its duplex structure also results in excellent resistance to stress corrosion cracking.
example, the super duplex grade, 2507, (S32750) shows a 50% loss of impact strength within a minute of exposure to temperatures in the 1650 to 1700ºF (900 to 925ºC) range, while the 2304 (S32304) grade will only show a loss after about 80 minutes. The high temperature nose for the 2507 (S32750), 2205 (S32205), and 2304 (32304) grades …

Duplex stainless steels have good weldability. All standard welding processes can be used. They are not quite as easily welded as the austenitic grades but low thermal expansion in duplex grades reduces distortion and residual stresses after welding. The recommended filler material for 2205 stainless steel is 2209.
