Duplex Stainless Steel Perforated Metal is popularly utilized steel in many commercial operations. It offers excellent potential and intense resistance to corrosion to the wide array of corrosive conditions. It offers very high resistance to chloride stress corrosion cracking, sea water corrosion and oxidation that occur at the high temperatures. This steel mesh strictly inhibits the local corrosion such as intergranular corrosion, pitting and crevice corrosion at temperatures about 350oC.
An easily weldable Duplex Stainless Steel 2205 has high machinability and large mechanical strength. It offers high fatigue strength and retains its features up to sub zero temperature levels.
