UNS S31803(S32205)Duplex Stainless Steel Wire Mesh
Duplex Stainless Steel Wire Mesh UNS S31803(S32205) this wire mesh is made of 21% chromium 2.5%molybdenum and 4.5% nitrogen nickel alloy. It has high strength good impact toughness and good overall and partial stress corrosion resistance. In the world it known as 2205 trade mark is SAF2205.Compared to 316L and 317L austenitic stainless steel S31803 duplex stainless steel is superior at pitting corrosion and crevice corrosion resistance. It has excellent corrosion resistance. Compared to austenitic it is with lower thermal expansion coefficient and higher thermal conductivity. S31803 duplex stainless steel wire mesh is widely used in chemistry seawater desalination equipment.
