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.

Sachiya Steel International is one of the well-known Manufacture and exporter of Super Duplex S32750 Wire Mesh, which can readily be used down to at least -50 Degree C. Super Duplex S32750 Hexagonal Wire Mesh is extremely corrosion resistant, work harden able alloys, where their microstructures consist of a mixture of austenite and ferrite phases.
As a result, Super Duplex S32760 Welding Wire Mesh display properties characteristic of both austenitic and ferritic stainless steels.
Combination of austenitic and ferritic properties in Super Duplex S32750 Netting Wire Mesh can mean some compromise when compared with pure austenitic and pure ferritic grades.Super Duplex S32760 Woven Wire Mesh is in most cases, tougher than ferritic stainless steels, where tooling and work surfaces must be thoroughly cleaned before use.
Strengths of Super Duplex S32750 Spring Steel Wire Mesh can in some cases be double that for austenitic stainless steels.
Whilst Super Duplex S32760 Fencing Wire Mesh is considered resistant to stress corrosion cracking, they are not as resistant to this form of attack as ferritic stainless steels.
However, the corrosion resistance of the least resistant Super Duplex S32750 Wire Mesh is greater than that for the most commonly used grades of stainless steels, i.e.
Sachiya Steel international is one of the well-known Manufacture and Exporter of Duplex S32205 Tube to Female Pipes, which is normally supplied in the solution – annealed condition.
Forging of these Duplex S31803 Tube Fittings should be started immediately the stock is removed from the reheat furnace and 25 % / 40 % reductions help to retain as much internal heat as possible.
For optimum corrosion resistance, forged parts of Duplex S32205 Tube Fittings should be subsequently annealed.
Treatment of these Duplex S31803 Compression Fittings is carried out at 2050 Degree F (1120 Degree C) followed by water quench or rapid air cool.The treatment in Duplex S32205 Compression Fittings is performed after hot working to ensure optimum corrosion resistance and between cold – working operations.
These Duplex S31803 Female Connector Fittings is considered moderate till difficult to machine, but can be machined using conventional methods.
Duplex S32205 Female Connector Fittings has a high work hardening rate, and efficient machining requires rigid and overpowered machines, sharp tools, preferably carbide – tipped, and heavy, constant feeds.
