Duplex Steel S31803 Pipe Fittings Manufacturer

Katariya Steel Distributors is a well-known name in this industry, involved in offering our respected clientele the finest quality range of Duplex Steel S31803 Butt Weld Pipe Fittings.

Duplex Steel S31803 Butt Weld Pipe Fittings are majorly composed of chromium, iron, nickel, molybdenum, manganese, silicon, and other required materials. The major selling point of duplex steel is that it is an exceptionally corrosion resistant alloy and can be worked hardened skillfully. Because of its nickel and chromium content, Duplex Steel S31803 has both austenitic and ferritic properties. The majority of the time, duplex steel is tougher than ferritic steel. There are cases of duplex steel having double the strength of austenitic stainless steel.

Duplex Steel S31803 Butt Weld Pipe Fittings' corrosion resistance is greater than most of the usually used stainless steel grades, that is 304 and 316. Duplex stainless steels are resistant to stress corrosion cracking, although not as much as ferritic stainless steels. It is also resistant to corrosion in warm waters and has high pitting resistance. One feature that distinguishes duplex steel from conventional austenitic grades of stainless steel is its magnetic nature.

Duplex Steel S31803 Butt Weld Pipe Fittings become brittle and partially or completely loses their ductility at a temperature above 300°C. It is more ductile than ferritic alloys at lower temperatures. It can maintain its usability at about -50°C. Its fabrication requires the use of only stainless steel alloy-specific tools. Although these alloys may be machined, the process is challenging due to their great strength. Welding is possible with duplex stainless steel. All standard welding procedures are usable.

Duplex Steel S31803 Butt Weld Fittings are used in a variety of applications, including oil field piping, food process equipment, pulp mill digesters, bleach washers, chemical process vessels, piping, heat exchangers, seawater pumps, and valves, FGD scrubber systems, seawater systems, and pollution control equipment. Katariya Steel Distributors also offer these products in customized sizes and shapes to the clients.
