Duplex-grade stainless steel derives its name from its two-phase microstructure consisting of austenitic and ferritic alloys in roughly equal parts (the exact metallurgic proportions vary by grade). As a result, duplex stainless steel grades combine the favorable qualities and benefits of boy alloy families while minimizing their weaknesses. No comparable alternatives deliver its cost-effective performance, high strength, and excellent corrosion resistance at its price point.
Grade 2507 stainless steel is a “super” duplex grade that offers better crevice and pitting corrosion resistance than conventional duplex grades and 300-series stainless steels. This nitrogen-enhanced alloy consists of 25% chromium, 4% molybdenum, 7% nickel, and low carbon amounts (up to 0.03%). This unique blend gives Grade 2507 robust mechanical strength, high mechanical strength, and superior resistance to uniform corrosion and stress corrosion cracking.
Like all duplex stainless steel, Grade 2507 offers superior yield strength. A lightweight gauge of this super duplex stainless steel provides a similar design strength to a thicker nickel alloy. This results in savings in weight and overall costs of fabrication.
Grade 2507 stainless steel has numerous benefits and advantages, including:
- Superior uniform corrosion tolerance
- High resistance to crevice corrosion and chloride pitting
- High yield strength, including twice the strength of austenitic and ferritic stainless steel grades
- Good weldability and formability
- Enhanced durability and toughness
- Low thermal expansion
- High-energy absorption
- Cost effective
- Easy to maintain and clean
While it possesses high thermal conductivity, the strength of this super duplex grade will degrade in long-term exposure to temperatures at or exceeding 600°F.
Grade 2507 Stainless Steel Plate Applications
Because of its superior overall corrosion resistance, Grade 2507 duplex stainless steel is frequently used in high-chloride and saltwater environments, oil and gas production, and chemical processing. It is commonly found in heat exchangers, piping, pressure vessels, food-processing equipment, cargo tanks for ships and trucks, and evaporators. Finally, its lightweight but high-yield strength makes it ideal for outdoor load-bearing applications (for example, pedestrian footbridges).
