SAF2507 stainless steel wire mesh product types, grades, uses

SAF2507 stainless steel wire mesh is also known as duplex stainless steel wire mesh, SAF2507 bidirectional stainless steel woven mesh, SAF2507 stainless steel square hole mesh, SAF2507 stainless steel screen, SAF2507 stainless steel filter, SAF2507 stainless steel mesh, SAF2507 stainless steel metal mesh, SAF2507 stainless steel metal wire mesh, SAF2507 stainless steel filter, etc.
SAF2507 stainless steel is a composite stainless steel material of ferrite-austenitic stainless steel, also called duplex stainless steel. Main components: 25Cr-7Ni-4Mo-0.27N. It combines the most beneficial properties of many ferritic steels and austenitic steels. Due to the high content of chromium and molybdenum in this steel, it has excellent resistance to pitting corrosion, crevice corrosion and uniform corrosion. The bidirectional microstructure ensures that the steel has a high resistance to stress corrosion cracking and high mechanical strength.

SAF2507 stainless steel wire mesh 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 dilute hydrochloric acid environment, with strong resistance to pitting corrosion and crevice corrosion.
