of Duplex Steel S31803 Seamless Pipes, Duplex Steel S32205 Seamless Pipes Supplier, Duplex Steel UNS S31803 Cold Drawn Seamless Pipes in India, Duplex Steel S31803/S32205 Seamless Pipes in India.

As a much-admired organization in the market, we as Kobs India are quite engaged in proposing a collection of Monel 400 Pipes as an exporter, manufacturer, supplier, and stockiest to our worldwide clients at reasonably priced costs. Also referred as UNS N04404 Pipes, Monel is a solid-solution binary alloy. As nickel and copper are mutually soluble in all proportions, it is a single-phase alloy.

Compared to steel, Monel is very difficult to machine as it work-hardens very quickly. It needs to be turned and worked at slow speeds and low feed rates. Meanwhile, we as well offer these Monel Alloy 400 pipes and tubes in customized thicknesses and sizes as per the precise requirements given by our valuable customers in international quality of standards.
