Duplex Steel metal suppliers


We are India based one of the leading manufacturers and suppliers of duplex steel metals and metal components like Rounds Bars, Flat Bars, Pipe & Tubes, Plates, Sheets, Fittings, Flanges and valves etc. Let's understand what duplex steel metal is and why it is been chosen by engineers for their project applications .Duplex stainless steels (DSS) metals and metal components are widely used in petrochemical projects, chemical plants, cellulose and nuclear plants across the world because of it's excellent austenitic-ferritic microstructure which in due offer an excellent combination of mechanical and corrosion resistance properties.

Many researchers have studied on duplex stainless steel metals and developed methods of detection and quantification of thermal embrittlement. Duplex steel metals are excellent corrosion resistant metal. This metal have high resistance to intergranular corrosion as well and even in chloride and sulfide environments, duplex steels metals exhibit very high resistance to stress corrosion cracking. There is one more upgraded metal i.e. super duplex steel metals, these super duplex graded metals are even more resistant to corrosion conditions.

The high chromium component in duplex steel metal that protects against corrosion causes embrittlement at temperatures above 300° Celsius temperature. At low temperatures duplex steel metals have better ductility than the ferritic and martensitic steels. Duplex steel can easily be used down up to at -50° Celsius temperature. Fabrication of all duplex steel metals should be done only with tools dedicated to duplex steel materials. Tooling and work surfaces must be properly cleaned before it's use. These precautions are necessary to avoid cross contamination of duplex steel by easily corroded metals that may discolour the surface of the fabricated product. Hardening by heat treatment of Duplex steel metals can not be done. However it can be work hardened. annealing or Solution treatment can be done by rapid cooling after heating duplex steel metal up to 1100° Celsius temperature.
