Duplex Alloy 2507 is a super duplex stainless steel with 25% chromium, 4% molybdenum and 7% nickel. It has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion. The high chromium, molybdenum and nitrogen levels provide excellent resistance to pitting, crevice and general corrosion. The impact strength is also high. Duplex Alloy 2507 is not recommended for applications which require long exposures to temperatures above 570 °F because of the risk of a reduction in toughness.
| Element | Composition, % |
|---|---|
| C | ≤0.030 |
| Mn | ≤1.20 |
| P | ≤0.035 |
| S | ≤0.020 |
| Si | ≤0.80 |
| Cr | 24.0–26.0 |
| Ni | 6.0–8.0 |
| Mo | 3.0–5.0 |
| N | 0.24–0.32 |
| Cu | ≤0.50 |
The nominal composition of alloy 2507 (S32750) is 25Cr-7Ni-4Mo-N. Compared to alloy 2205 (S32205), alloy 2507 has higher chromium content, which results in increased corrosion resistance. Since chromium promotes the body-centered cubic structure of iron as a ferrite former, more nickel is necessary to promote the the formation of austenite to balance the effect of higher chromium. Higher chromium also promotes the formation of detrimental intermetallic phases, which are sensitive to 475°C embrittlement because of precipitation of the chromium-rich α’ phase, and to embrittlement by sigma, chi and other phases at higher temperatures. Alloy 2507 (S32750) also has higher nitrogen content, which not only promotes the formation of austenite and increases the strength, but also delays the formation of intermetallic phases enough to permit processing and fabrication of the duplex grade.
