2507 Stainless Steel SheetAt Jiangsu Daxun Alloy Co., Ltd., we proudly present our Baosteel 2507 Stainless Steel Plate, a super duplex alloy blending 50% austenite and 50% ferrite. Originating in the U.S. in the 1940s, it has evolved to its third generation, boasting a remarkable yield strength of 400-550MPa-double that of standard stainless steel. This efficiency allows for material savings and lower production costs. In corrosive environments, particularly those with seawater and high chloride ion content, our duplex steel excels against pitting, crevice corrosion, stress corrosion, and fatigue, rivaling even high-alloy austenitic stainless steels. Daxun Alloys delivers this versatile duplex 2507 stainless steel in various forms and sizes, all conforming to international standards like ASTM, ASME, EURONORM, and AFNOR.
DUPLEX 2507 STAINLESS STEEL Plate
Daxun Alloys proudly stocks Duplex 2507, a super duplex stainless steel plate composed of 25% chromium, 4% molybdenum, and 7% nickel. This advanced alloy is perfect for high-strength, corrosion-resistant applications in chemical processing, petrochemical, and seawater equipment. It offers outstanding resistance to chloride stress corrosion cracking, excellent thermal conductivity, and a low coefficient of thermal expansion. The elevated levels of chromium, molybdenum, and nickel ensure superior resistance to pitting, crevices, and general corrosion.
GENERAL PROPERTIES
Duplex 2507 (UNS S32750) from Daxun Alloys is a super duplex stainless steel featuring 25% chromium, 4% molybdenum, and 7% nickel. Engineered for demanding environments requiring high strength and exceptional corrosion resistance, it's ideal for chemical processes, petrochemical, and seawater equipment. This steel excels in resisting chloride stress corrosion cracking, offers high thermal conductivity, and maintains a low coefficient of thermal expansion. Its high chromium, molybdenum, and nickel content provide excellent resistance to pitting, crevices, and general corrosion.
Applications
- Oil and gas industry equipment
- Offshore platforms, heat exchangers, process and service water systems, fire-fighting systems, injection and ballast water systems
- Chemical process industries: heat exchangers, vessels, and piping
- Desalination plants, high-pressure RO plants, and seawater piping
- Mechanical and structural components: high strength, corrosion-resistant parts
- Power industry: FGD systems, utility, and industrial scrubber systems, absorber towers, ducting, and piping
Standards
ASTM/ASME...... A240 - UNS S32750
EURONORM...... 1.4410 - X2 Cr Ni MoN 25.7.4
CORROSION RESISTANCE
General Corrosion
- The high chromium and molybdenum content of 2507 makes it highly resistant to uniform corrosion by organic acids such as formic and acetic acid.
- Offers excellent resistance to inorganic acids, particularly those containing chlorides.
- Suitable for use in dilute hydrochloric acid.
- Pitting should not be a concern below the borderline in this figure, although crevices should be avoided.
Intergranular Corrosion
- The low carbon content significantly reduces the risk of carbide precipitation at grain boundaries during heat treatment.
- Extremely resistant to carbide-related intergranular corrosion.
Stress Corrosion Cracking
- The duplex structure of the Baosteel 2507 Stainless Steel Plate ensures unparalleled resistance to chloride stress corrosion cracking (SCC), making it a reliable choice for challenging environments.
- Surpassing the 2205 grade in both corrosion resistance and strength, 2507 sets a new benchmark for durability and performance.
- Baosteel 2507's exceptional utility shines in offshore oil and gas sectors, particularly in wells with either naturally high brine levels or those enhanced with brine injections for increased recovery.
Pitting Corrosion
- Various testing methodologies can be employed to determine the pitting resistance of steel in chloride-rich solutions, ensuring reliability.
Crevice Corrosion
- Baosteel 2507 demonstrates a high resistance to crevice corrosion, enhancing its longevity in harsh conditions.
Hot Forming
For optimal performance, 2507 should be hot worked within the temperature range of 1875°F to 2250°F, followed by a solution anneal at a minimum of 1925°F and a rapid air or water quench.
Cold Forming
Cold working Baosteel 2507 is compatible with most standard stainless steel forming processes. Given its higher yield strength and lower ductility compared to austenitic steels, fabricators might need to apply more force, use a larger bending radius, and allow for a greater springback margin. Procedures like deep drawing and stretch forming are more challenging with 2507 than with austenitic stainless steel. If forming involves more than 10% cold deformation, a solution anneal and quench are recommended.
Heat Treatment
Post hot or cold forming, Baosteel 2507 should undergo solution annealing and quenching at a temperature of at least 1925°F, followed by a rapid air or water quench. To maximize corrosion resistance, heat-treated products should be pickled and rinsed.
Welding
Baosteel 2507 boasts excellent weldability and can be joined to itself or other materials using various techniques such as shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW), plasma arc welding (PAW), flux cored wire (FCW), or submerged arc welding (SAW). For desired duplex weld structures, use 2507/P100 filler metal when welding 2507.
2507 is not required, except to prevent condensation on cold metal. The Interpass
Baosteel 2507 Grade Stainless Steel Sheets in a Variety of Finishes
Our Baosteel stainless steel sheets are available in a spectrum of elegant finishes: from brushed to 2B smooth, and the pristine 8K mirror finish.
