Characteristics and uses of 2507 duplex steel wire mesh-Anping County Maoqun Wire Mesh Manufacturing Co., Ltd.

2507 Duplex Steel Wire Mesh is also known as UNS S32750 stainless steel wire mesh, 2507 Duplex Steel Screen, 2507 Duplex Steel Filter Mesh, 2507 Duplex Steel Woven Mesh, 2507 Duplex Steel Filter Mesh, 2507 Duplex Steel Square Hole Mesh.

Mechanical properties: tensile strength: σb ≥ 795Mpa, yield strength σb ≥ 550Mpa: elongation: δ ≥ 15%, hardness ≤ 310 (HB)

Corrosion resistance and main use environment: The higher chromium and molybdenum content of 2507 duplex steel makes it have strong overall corrosion resistance to organic acids such as formic acid and acetic acid. 2507 duplex steel also has strong corrosion resistance to inorganic acids, especially those containing chlorides. Compared with 904L, 2507 duplex steel has stronger corrosion resistance to diluted sulfuric acid mixed with chloride ions. 904L is an alloy in the austenitic state, specially designed to resist pure sulfuric acid corrosion. 316L cannot be used in hydrochloric acid environment, it may suffer from local corrosion or overall corrosion. 2507 duplex steel is used in diluted hydrochloric acid environment and has strong resistance to pitting corrosion and crevice corrosion.

2507 Duplex Steel Wire Mesh Corrosion Resistance

1. General corrosion: The higher chromium and molybdenum content of SAF 2507 makes it have strong overall corrosion resistance to organic acids such as formic acid and acetic acid. SAF2507 alloy also has strong corrosion resistance to inorganic acids, especially those containing chlorides.

Compared with 904L, SAF2507 has stronger corrosion resistance to diluted sulfuric acid mixed with chloride ions. 904L is an alloy in the austenitic state, specially designed to resist pure sulfuric acid corrosion.

316L grade cannot be used in hydrochloric acid environment, it may be subject to local corrosion or overall corrosion. SAF2507 can be used in diluted hydrochloric acid environment, with strong resistance to pitting and crevice corrosion.

2. Intergranular corrosion: The lower carbon content of nSAF 2507 greatly reduces the risk of carbide precipitation between grains during heat treatment. Therefore, this alloy has a strong ability to resist intergranular corrosion related to carbides.

3. Stress corrosion cracking: The duplex structure of SAF 2507 makes it highly resistant to stress corrosion cracking. Due to its higher alloy content, the corrosion resistance and strength of SAF 2507 are better than those of 2205.
