Description of UNS S31803 Duplex Wire Mesh
Duplex Stainless Steel (DSS) refers to stainless steel in which
ferrite and austenite each account for about 50%. Generally, the
content of the smaller phase needs to be at least 30%. In the case
of low C content, the Cr content is 18%~28% and the Ni content is
3%~10%.
This type of steel has the characteristics of both austenitic and
ferritic stainless steel. Compared with ferrite, its intergranular
corrosion resistance and welding performance are significantly
improved. Compared with austenitic stainless steel, it has high
strength and significantly improved resistance to intergranular
corrosion and chloride stress corrosion.
Duplex stainless steel has excellent pitting corrosion resistance
and is also a nickel-saving stainless steel.
2205 duplex stainless steel is an economical corrosion-resistant
stainless steel.
2507 super duplex stainless steel has excellent resistance to
pitting corrosion, crevice corrosion and uniform corrosion.
