Sachiya Steel International is one of the well-known Manufacture and Exporter of Duplex S32205 Wire Mesh , which has superior corrosion resistance compares to SS 304 and SS 316. The general use for our Duplex S31803 Hexagonal Wire Mesh is in the manufacture of chemicals such as sulphuric and phosphoric acids. General corrosion resistance of this Duplex S32205 Welding Wire Mesh is characterized by uniform attack on a flat surface in contact with a corrosive media.
Pitting corrosion resistance increases in our Duplex S31803 Netting Wire Mesh with increasing chromium, molybdenum, and nitrogen contents. As such, this Duplex S32205 Woven Wire Mesh shows higher PREN (Pitting Resistance Equivalent Number) values than the typical austenitic grades. When exposed to standard medium of H2S sour gas for duration of 720 hours, our Duplex S31803 Spring Steel Wire Mesh has results that are comparable to a super – austenitic 904L.
This Duplex S32205 Fencing Wire Mesh is chemically balanced to obtain a two phase ferrite and austenite structure containing between 40 % to 60 % ferrite. A typical structure of our Duplex S31803 Fencing Wire Mesh is shown when the material was hot rolled and solution annealed. This Duplex S32205 Spring Steel Wire Mesh is sensitive to the precipitation of inter – metallic phases that can degrade the corrosion resistance and mechanical properties. Meanwhile, the high strength of our Duplex S31803 Woven Wire Mesh can pose problems.
