UNS S32750 or DIN W.Nr. 1.4410, Super Duplex 2507 is a super duplex stainless steel containing 25% Chromium, 4% Molybdenum and 7% Nickel, designed for demanding applications requiring superior strength and corrosion resistance. Examples include chemical process, petrochemical and seawater equipment. The nominal composition of Alloy 2507 (S32750) is 25Cr-7Ni-4Mo-N. Alloy 2507 has a higher chromium content compared to Alloy 2205 (S32205), resulting in improved corrosion resistance. Since chromium promotes the body-centered cubic structure of iron as a ferrite former, more nickel is needed to promote austenite formation to balance the effect of higher chromium. Higher chromium content also promotes the formation of harmful intermetallic phases, which are susceptible to embrittlement at 475°C due to the precipitation of the chromium-rich α' phase, and to σ, chi and other phases at higher temperatures. sensitive. Alloy 2507 (S32750) also has a higher nitrogen content, which not only promotes the formation of austenite and increases strength, but also delays the formation of intermetallic phases sufficiently to allow processing and fabrication of duplex steel grades.
