We have our new gasket manufacturing facility. Our spiral wound gasket widely use in oil and gasket industrial ,chemical industrial, mining industrial ,power station and most industrial factory

S31083 (Duplex 2205 )is a nitrogen enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels.

Corrosion Resistance:
2205 duplex stainless steel is a cost effective solution for many applications where the 300 series stainless steels are susceptible to chloride stress corrosion cracking. Stress corrosion cracking occurs when stainless steels are subjected to tensile stress, while in contact with solutions containing chlorides. Increasing temperatures also increase the susceptibility of stainless steels to stress corrosion cracking.
