1.Composition and performance of duplex 2507 stainless steel

Duplex 2507 stainless steel is a highly alloyed duplex stainless steel grade, also known as UNS S32750. It contains higher amounts of chromium, molybdenum, and nitrogen compared to standard duplex stainless steels, providing exceptional strength, corrosion resistance, and resistance to pitting and crevice corrosion.

Composition of duplex 2507 stainless steel

Element	Composition Range (%)
Chromium (Cr)	24.0 – 26.0
Nickel (Ni)	6.0 – 8.0
Molybdenum (Mo)	3.0 – 5.0
Nitrogen (N)	0.24 – 0.32
Carbon (C)	0.030 max
Silicon (Si)	1.00 max
Manganese (Mn)	2.00 max
Phosphorus (P)	0.035 max
Sulfur (S)	0.020 max

Chromium (Cr): Chromium is the primary alloying element in stainless steel and contributes to its corrosion resistance. In Duplex 2507, chromium content is typically around 24-26%.
Nickel (Ni): Nickel is another essential element in stainless steel that enhances its resistance to corrosion and provides stability to the austenite phase. The nickel content in Duplex 2507 is approximately 6-8%.
Molybdenum (Mo): Molybdenum adds further corrosion resistance to stainless steel, particularly in chloride-rich environments. Duplex 2507 contains about 3-5% molybdenum.
Nitrogen (N): Nitrogen is an important element in Duplex 2507, as it enhances the material’s strength and contributes to its ability to form a stable dual-phase microstructure.
Carbon (C): The carbon content in Duplex 2507 is typically kept low to avoid the formation of harmful carbides that could impair its corrosion resistance.
Silicon (Si): Silicon helps improve the material’s resistance to oxidation and scaling at high temperatures.
Manganese (Mn): Manganese is added to enhance the material’s strength and toughness.
Phosphorus (P) and Sulfur (S): These elements are generally kept at low levels to maintain the material’s corrosion resistance and mechanical properties.

The unique combination of these elements in Duplex 2507 stainless steel results in a dual-phase microstructure consisting of both austenite and ferrite phases. This duplex structure provides the material with excellent corrosion resistance, high strength, and good ductility, making it suitable for various challenging applications.

Performance of Duplex 2507 Stainless Steel

Property	Performance of Duplex 2507 Stainless Steel
Corrosion Resistance	Excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking (ClSCC) in aggressive environments, including marine and acidic conditions.
Mechanical Strength	Higher mechanical strength compared to standard austenitic and ferritic stainless steels, providing excellent tensile and yield strength.
Ductility and Toughness	Good ductility and toughness, allowing it to withstand mechanical impacts and stresses without failure.
Thermal Conductivity	Higher thermal conductivity compared to austenitic stainless steels.
Erosion and Abrasion Resistance	Resistant to erosion and abrasion, making it suitable for applications in mining and offshore industries.
Sulfide Stress Corrosion Cracking (SSC) Resistance	Exhibits good resistance to sulfide stress corrosion cracking in sour gas environments, ideal for oil and gas applications.
Biocompatibility	Displays good biocompatibility, making it suitable for certain medical and bioengineering applications.
Cost-Effectiveness	Offers a cost-effective alternative to high-nickel super-austenitic stainless steels, providing comparable or superior performance in specific applications.
Weldability	Readily weldable with appropriate techniques, but requires careful heat input control and post-weld treatments to maintain properties.
Thermal Expansion	Lower thermal expansion coefficient compared to austenitic stainless steels, providing dimensional stability under varying temperatures.
Range of Applications	Suitable for various industries, including chemical processing, oil and gas, marine, desalination, and pulp and paper, among others.
