Chemical composition of Alloy 2507
The formula ofAlloy 2507 was developed to provide superior performance both mechanically and chemically. Typical composition includes:
- Chromium (Cr): 24-26%
- Nickel (Ni): 6-8%
- Molybdenum (Mo): 3-5%.
- Nitrogen (N): 0.24-0.32%.
- Iron (Fe): balanced
This combination ensures a high PREN index (>40), a parameter that measures resistance to pitting and cracking corrosion.
Mechanical properties of Alloy 2507
Compared with conventional austenitic stainless steels such as AISI 316L, Alloy 2507 offers significantly superior performance:
| Properties | Alloy 2507 | AISI 316L |
|---|---|---|
| Tensile strength (Rm) | ≥ 800 MPa | 500-700 MPa |
| Elastic limit (Rp0.2) | ≈ 550 MPa | 300-450 MPa |
| Elongation | ≥ 25% | ≥ 40% |
| Resistance to pitting (PREN) | > 40 | 24-27 |
These values highlight the suitability of Super Duplex 2507 for use in highly corrosive and high-pressure environments.
Industrial applications of Alloy 2507
Because of its qualities, Alloy 2507 is in demand in many industries:
- Offshore sector: piping, fittings, hardware, and submerged structures in seawater
- Chemical industry: processing plants with acids and aggressive solutions
- Energy: turbines, generators and heat exchangers exposed to extreme thermal cycles
- Naval: components subject to salt spray and localized corrosion
- Infrastructure: support systems in environments subject to high humidity and salt contamination
The combination of strength and durability helps to reduce maintenance costs and provide greater operational safety.
