Metinox Overseas is a popular supplier and distributor of Duplex UNS S31803 Pipe Fittings. It is the most highly used duplex grade. These pipe fittings are offering several features such as durability, finish surface, dimensions, lengths, reusable, and many more. Duplex UNS S31803 Pipe Fittings are nitrogen improved stainless steel that was made to combat oxidation issues with stainless steel series of 300. Duplex is a grade of stainless steel family which is not completely ferrite not fully austenitic. The structure of S31803 contains austenitic with some ferrite phase. In the environment of annealed, S31803 is the highly used grade in the family of Duplex Stainless Steel.

The benefits of Duplex UNS S31803 Pipe Fittings is it’s the combination of great quantities of ferritic alloy like high strength, stress oxidation crevice resistant with those austenitic like oxidation resistant and easy to fabrication. Generally the use of UNS S31803 Pipe Fittings should be worked at the below temperature of 600 degrees F. the elevated temperature can make embrittled the UNS S31803 grade.
The nitrogen, chromium, and molybdenum are the combination that offers the better resistance of Duplex UNS S31803 to pitting oxidation and chloride crevice. Meanwhile, the resistance is highly necessary for applications to use, such as closed-loop water systems, bleaching operations, brackish water, marine environment, and some food processing applications. However, the nitrogen, chromium, and molybdenum combination of Duplex UNS S31803 offer oxidation resistance to common stainless steels like 316L and 317L in most atmospheres.
