Unparalleled Advantages of the 2507 Stainless Steel Plate:
- The 2507 stainless steel plate boasts superior resistance to pitting corrosion with an impressive PREN value of up to 43. This exceptional corrosion resistance extends to stress corrosion cracking (SCC), crevice corrosion, and general corrosion, making Duplex 2507 steel an incredibly versatile and reliable option for numerous demanding applications in harsh environments.
- With a yield strength double that of the 300 series stainless steel, the 2507 stainless steel plate allows for the use of thinner sections under identical load conditions. This strength advantage not only enhances structural integrity but also significantly reduces material costs for equipment.
- Its yield and tensile strength, both twice that of ordinary stainless steel, substantially improve wear resistance.

CORROSION RESISTANCE
General Corrosion
- The high chromium and molybdenum content of Duplex 2507 make it extremely resistant to uniform corrosion caused by organic acids such as formic and acetic acid.
- It provides excellent resistance to inorganic acids, especially those containing chlorides.
- Suitable for use in dilute hydrochloric acid environments.
- Pitting is not a concern below the borderline in this figure, though crevices should be avoided.
Intergranular Corrosion
- The low carbon content significantly reduces the risk of carbide precipitation at grain boundaries during heat treatment.
- Highly resistant to carbide-related intergranular corrosion.
Stress Corrosion Cracking
- The duplex structure of the 2507 stainless steel plate offers unparalleled resistance to chloride stress corrosion cracking (SCC), ensuring longevity and reliability.
- Experience superior corrosion resistance and strength with our 2507 stainless steel plate, outperforming the 2205 grade in every aspect.
- Ideal for the demanding environments of offshore oil and gas applications, the 2507 stainless steel plate thrives in wells with naturally high brine levels or where brine has been injected to enhance recovery.
Pitting Corrosion
- Utilize various testing methods to accurately determine the pitting resistance of steels in chloride-containing solutions, ensuring the highest quality and durability.
Crevice Corrosion
- The 2507 stainless steel plate possesses exceptional resistance to crevice corrosion, maintaining its integrity under challenging conditions.
Hot Forming
For optimal results, hot work the 2507 stainless steel between 1875°F and 2250°F, followed by a solution anneal at a minimum of 1925°F, and a rapid air or water quench.
Cold Forming
Cold working 2507 stainless steel is seamlessly compatible with most standard stainless steel forming processes. Due to its higher yield strength and lower ductility compared to austenitic steels, fabricators may require increased forming forces, larger bending radii, and allowances for springback. Processes like deep drawing and stretch forming are more challenging with 2507. For deformation exceeding 10%, a solution anneal and quench is recommended for optimal results.
Heat Treatment
Following hot or cold forming, 2507 should be solution annealed at a minimum of 1925°F and rapidly quenched with air or water. To ensure superior corrosion resistance, heat-treated products should undergo pickling and rinsing.
Welding
The 2507 stainless steel plate exhibits exceptional weldability, allowing it to be joined to itself or other materials using techniques such as SMAW, GTAW, PAW, FCW, or SAW. For optimal duplex weld structure, utilize 2507/P100 filler metal when welding.
2507 is not typically required, except to prevent condensation on cold metal. The Interpass
2507 Grade Stainless Steel Sheets in a Variety of Finishes
Our 2507 stainless steel sheets come in a range of stunning finishes, including brushed, 2B smooth, and 8K mirror, catering to diverse aesthetic and functional needs.
