Let you know about duplex stainless steel--2507
Duplex Stainless Steel (DSS) is a stainless steel containing two phase structures of austenite and ferrite. This type of steel has the characteristics of both austenite and ferrite stainless steel. 2507 is a widely used stainless steel. Duplex stainless steel. Below, the editor of Aozhan will discuss with you the application fields and advantages of 2507 duplex stainless steel.
2507 duplex stainless steel is developed on the basis of the second generation duplex stainless steel 2205. Its corrosion resistance and strength are better than 2205. The higher chromium and molybdenum content makes it more resistant to organic acids such as formic acid and acetic acid. It has excellent overall corrosion resistance and strong corrosion resistance against inorganic acids, especially those containing chlorides.
The lower carbon content of 2507 greatly reduces the risk of carbide precipitation in the intergranular spaces during heat treatment. Therefore, it also has strong resistance to carbide-related intergranular corrosion.
The dual-phase structure ensures that the steel has high resistance to stress corrosion cracking and high mechanical strength.
The advantages of fasteners made of 2507 material are: good resistance to intergranular corrosion and crevice corrosion, high strength, resistance to chloride stress corrosion, and weldability. It is widely used in the pulp and paper industry, seawater desalination, flue gas purification, Heat exchangers, chemical tanker piping systems, seawater systems, etc.
