2205 Duplex Spiral Wound Gaskets
Item No.:ZD-G1202/2205
Description: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.
