Qunkun Duplex Stainless Steel Wire Mesh UNS S31803(S32205)

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

Pressure vessels, tanks, high pressure pipe, heat exchanger( chemical processing industry)

Oil and gas pipelines, heat exchangers pipe fittings

Sewage treatment system

Food processing equipment etc
