What is 2507 Super Duplex stainless steel and what are its properties, applications and benefits? The following is a detailed introduction.
What is 2507 Stainless Steel?
2507 stainless steel is a ferritic-austenitic (duplex) super duplex stainless steel known for its exceptional corrosion resistance, high strength, and durability. Its chemical composition (25% Cr, 7% Ni, 4% Mo, and 0.27% N) provides superior performance in harsh environments, making it ideal for demanding industrial applications.
Key Properties of 2507 Stainless Steel
2507 super duplex stainless steel offers outstanding corrosion resistance, demonstrating excellent performance against pitting corrosion, crevice corrosion, and stress corrosion cracking. This is particularly evident in chloride-rich environments such as seawater applications.
The material exhibits superior mechanical strength with a minimum tensile strength of 800 MPa and yield strength of 550 MPa, while maintaining an elongation of at least 15%. These properties make it approximately 50% stronger than conventional austenitic stainless steels.
With a maximum hardness rating of 290 HBW, 2507 stainless steel maintains an optimal balance between durability and machinability. The steel achieves its best combination of mechanical properties and corrosion resistance when solution-treated at 1050°C, where it demonstrates optimal thermal stability.
Applications of 2507 Stainless Steel
Due to its high strength and corrosion resistance, 2507 duplex stainless steel is widely used in:
2507 stainless steel is extensively utilized in the oil and gas industry, where it serves critical functions in offshore platforms, subsea pipelines, and various underwater equipment components. Its exceptional corrosion resistance makes it particularly valuable for chemical processing applications, including reactors, heat exchangers, and storage tanks for corrosive acids.
In desalination plants, this super duplex stainless steel proves indispensable for seawater handling systems and reverse osmosis components that require long-term durability in saline environments. The material also plays a vital role in pollution control systems, especially in flue gas desulfurization (FGD) units and waste gas treatment installations where resistance to aggressive chemicals is paramount.
Marine engineering applications benefit significantly from 2507 stainless steel's properties, with common uses including shipbuilding, propeller shafts, and various underwater components that must withstand constant exposure to seawater while maintaining structural integrity.
