Overview

2507 Super Duplex stainless steel (UNS S32750) is a high-performance duplex stainless steel designed for applications requiring exceptional corrosion resistance, high strength, and excellent durability in aggressive environments.

With a balanced austenitic-ferritic microstructure, 2507 offers superior resistance to pitting, crevice corrosion, chloride stress corrosion cracking, and erosion compared with conventional stainless steels such as 304, 316L, and standard duplex 2205.

Due to its outstanding performance in harsh conditions, 2507 Super Duplex stainless steel is widely used in offshore oil and gas, marine engineering, chemical processing, desalination plants, heat exchangers, and high-pressure piping systems.

At Yunming Metal, we supply a complete range of 2507 Super Duplex stainless steel products, including seamless tubes, welded tubes, pipes, plates, bars, flanges, and fittings. Products are available according to international standards and customer specifications.

Why Choose 2507 Super Duplex Stainless Steel?

2507 Super Duplex provides excellent mechanical properties and corrosion resistance for demanding industrial applications.

Superior Corrosion Resistance

2507 offers outstanding resistance to:

• Pitting corrosion
• Crevice corrosion
• Chloride corrosion
• Stress corrosion cracking (SCC)

making it ideal for seawater and offshore environments.

---

High Mechanical Strength

Compared with austenitic stainless steels, 2507 provides significantly higher yield strength, allowing:

• Reduced wall thickness
• Lower material weight
• Improved equipment efficiency

---

Excellent Chloride Resistance

The high chromium, molybdenum, and nitrogen content provides excellent protection in chloride-rich environments.

---

High PREN Value

2507 has a PREN (Pitting Resistance Equivalent Number) typically above 40, providing superior corrosion resistance compared with 316L and 2205 duplex stainless steel.

---

Long Service Life

Its combination of strength and corrosion resistance reduces maintenance requirements and improves reliability in severe operating conditions.
