Duplex Steel fittings

Duplex Stainless steel metal was firstly developed about 70 years ago in Sweden for use in the sulfite paper industry application.

These Duplex alloys were originally developed or invented to combat corrosion problems caused by chloride-bearing cooling waters and other aggressive chemical process fluids.

The nitrogen alloyed duplex stainless steel are particularly suitable for applications covering the -50oF / +600oF temperature range. Temperatures outside this range may be considered but need some restrictions, particularly for welded structures.

“Duplex” metal is mixed microstructure with about equal proportions of “ferrite” and “austenite”. Duplex stainless steels are a family of many grades under one umbrella, which range in corrosion performance depending on their alloy content. The chemical composition based on high contents of Chromium and Molybedium, improves pitting corrosion resistance and intergranular, respectively.

With significant addition of nitrogen gas as an alloying agent, improved toughness in the heat-affected zones of welds and excellent chloride corrosion resistance both was achieved thus quickly becoming the best metal of stainless steels, accounting for more than 75% of duplex steel metal consumption.

It has got popular rapidly because of its cost-based combination as the replacement of the nickel content with the addition of nitrogen which is comparatively very less expensive. With this duplex steel metals we can manufacture many metal components like duplex steel tube fittings, duplex steel butt weld fittings, duplex steel high pressure (Screwed) fittings etc.

Duplex Steel High Pressure Fittings

Duplex stainless steel high pressure fittings are being used where applicable pressure is very high and critical. If the application is not critical and only pressure is an important factor than other grades of stainless steel can be used. There are many duplex steel high pressure fittings products like Elbow, Tee, Three peaces Unions, Cross etc. We are manufacturing the same from 150 to 10000 PSI.

Why Duplex stainless Steel fittings

Duplex stainless steel fittings are the best substitutes of stainless steel fittings because of two main reasons and that is first it is less nickel carring metal which have a direct impact on the price and economy of this metal consumption and second one is it's best sustainability in corrosive conditions.
