Introduction of UNS S31803(S32205) Super Duplex Stainless Steel Wire Mesh
S31803 duplex stainless steel wire mesh is made of 21% chromium, 2.5% molybdenum and 4.5% nitrogen nickel alloy. It has a high strength, good impact toughness and excellent overall and partial stress corrosion resistance. It is known as 2205, and the trade mark is SAF2205.

Features of UNS S31803(S32205) Super Duplex Stainless Steel Wire Mesh:
Compared to 316L and 317L austenitic stainless steel, S31803 duplex stainless steel is superior at pitting corrosion and crevice corrosion resistance. It has an excellent corrosion resistance. Compared to austenitic, it has a lower thermal expansion coefficient and higher thermal conductivity. S31803 duplex stainless steel wire mesh is widely used in chemistry and seawater desalination equipment.
