We are providing these Flanges to our buyers in various dimensions, specifications, sizes, forms, finishes, etc. Also, these Flange is made available to the buyers in customized specifications according to the needs of our buyers based upon applications in industries.


We, Nitron Alloys Overseas, does the manufacturing of these Duplex Steel UNS S31803 Slip On Flange by using the pure and tested quality of raw materials. Once the alloy is examined and permitted for its usage for the Flange development by the quality checker, it is made in use. We are accurately designing the ranges of these Flanges as per set manufacturing standards and global quality standards. The development of the product is executed under the proper guidance of professionals. We have the best quality controllers that are checking the product quality based upon the set parameters.


Our high-grade Duplex Steel UNS S31803 Slip On Flange contains a more significant amount of chromium, which enhances the corrosion resistance. These Flanges have Carbon, Manganese, Silicon, Phosphorous, Sulphur, Chromium, Monel, Nickel, Iron, and much more. All these materials help to increase properties like density, good tensile strength, high yielding strength, and many more. Our Flanges have good low-temperature toughness. With moderate to excellent corrosion resistance, our high-grade Flanges are having the combination of good mechanical strength and flexibility.


We, Nitron Alloys Overseas, are also performing quality checking to play a significant role in the entire process of product development. The testing of the manufactured ranges of these Duplex Steel UNS S31803 Slip On Flange is done to ensure that we don’t supply or export the poor quality of these flanges. We are performing various destructive and non-destructive tests on these Flanges to ensure different quality parameters. And then we are packing these high-grade Duplex Steel UNS S31803 Slip On Flange with suitable packaging material for safe and damage-free doorstep service.
