Kiah Metallurgical Indian Exporters is a renowned supplier and exporter of Duplex S31803 Sheets Plates Coils, which has yield strength, double that of conventional austenitic stainless steels. These Duplex S31803 Plates resist sulfide stress corrosion and chloride environments and have high chrome/chromium content (22 %) and moderate nickel content (5.5 %). Our Duplex S31803 Coils are used for Chemical processing, transport, and storage; Marine and other high chloride environments; and Oil and Gas exploration and processing equipment. These Duplex Steel UNS S31803 Plates are in most cases, tougher than Ferritic stainless steels; where strengths of the same can in some cases double that for austenitic stainless steels. Our Duplex Steel UNS S31803 Coils have first-rate sulfide stress corrosion resistance, excellent impact toughness, high strength, good workability, and weldability.


Duplex Steel UNS S31803 Sheets & Plates

This leads to reduced plate thicknesses of these Duplex Stainless Steel S31803 Sheets being used in fabrications reducing the weight which is of particular significance in items such as pressure vessels, storage tanks, and structural applications such as bridges. Typical applications of our Duplex Stainless Steel S31803 Plates include pipework, pumps, valves, flanges etc. together by means of a number of applications in the brewing, power generation, oil and gas, and chemical engineering industries. Often referred to as the workhorse grade, these Duplex Stainless Steel S31803 Coils is the most widely used grade and alloy in the duplex family of stainless steels.
