At Daxun, we are pleased to provide customers with high-quality super duplex 2507 stainless steel plates, which are a 50/50 mixture of austenite and ferrite, stronger than pure austenite or iron alloys. Since its birth in the United States in the 1940s, it has developed to the third generation, and its main feature is that the yield strength can reach 400-550MPa, which is twice that of ordinary stainless steel, so the duplex plate can save materials and reduce equipment manufacturing costs. In terms of corrosion resistance, especially in media environments (such as seawater, high chloride ion content), the resistance to pitting, crevice corrosion, stress corrosion, and corrosion fatigue of duplex stainless steel is better than that of ordinary austenitic stainless steel, and is comparable to high-alloy austenitic stainless steel. Daxun Alloys provides duplex 2507 stainless steel in a variety of forms and sizes, all of which comply with industry and international standards such as ASTM, ASME, EURONORM and AFNOR.
Daxun’s inventory now includes Duplex 2507 stainless steel plate, an excellent super duplex stainless steel containing 25% chromium, 4% molybdenum and 7% nickel. This plate is designed for applications requiring excellent strength and corrosion resistance; such as applications in the chemical processing industry, petrochemical and seawater equipment industries. This grade of plate has excellent resistance to chloride stress corrosion cracking, high thermal conductivity and low thermal expansion coefficient. The high chromium, molybdenum and nickel content provides excellent resistance to pitting, crevice corrosion and general corrosion. Ask Daxun today.

2507 stainless steel plate advantages:
- 2507 stainless steel plate has high resistance to pitting corrosion, with a PREN value of up to 43, and has excellent corrosion resistance. Duplex 2507 steel plate also exhibits excellent resistance to other forms of corrosion, including stress corrosion cracking (SCC), crevice corrosion, and general corrosion. These combined corrosion resistance properties make duplex 2507 a versatile and reliable choice for a wide range of applications in harsh environments.
- 2507 has a yield strength that is twice that of 300 series stainless steel. This strength advantage allows the use of thinner steel sections under the same load conditions and reduces the material cost of the equipment.
- It has a yield strength and tensile strength that is twice that of ordinary stainless steel. This significantly improves wear resistance.

Yes. Duplex 2507 stainless steel has good weldability and can be joined to itself and other materials using a variety of welding methods, including SMAW (shielded metal arc welding), PAW (plasma arc welding), GTAW (gas tungsten arc welding), FCW (flux cored wire) and SAW (submerged arc welding). When welding 2507, it is best to use 2507/P100 filler metal.
Yes. Although duplex 2507 stainless steel is very corrosion resistant, it can still rust in extreme situations. It is, nevertheless, less likely to rust than other varieties of stainless steel. The high quantities of chromium and molybdenum in 2507 make it extremely resistant to uniform corrosion caused by organic acids like formic and acetic acid. The exceptional corrosion resistance of 2507 steel makes it suited for use in corrosive conditions such as seawater, acids, and chemicals, where it retains its integrity and does not rust or corrode quickly.
Yes, the presence of ferritic grains within its composition renders 2507 duplex stainless steel a magnetic material.
Yes, duplex 2507 is an expensive metal. This is primarily due to its high alloying content, but it comes with the added benefit of exceptional corrosion resistance in extreme environments.
