S31803 Duplex Bar is 22% chromium duplex (austenitic/ferritic) steel with moderate to good strength and good general corrosion/stress corrosion/cracking resistance. It resists chloride environments and sulphide stress corrosion and is roughly double the strength of standard austenitic stainless steels. S31803 can be used successfully as an alternative to 300 serious austenitic stainless steel in most applications where higher mechanical strength/lower weight is required. S31803 is readily weldable using many of the standard electric arc welding processes but oxyacetylene welding is not recommended because carbon pickup in the weld metals may occur.
Typical applications: Pumps, valves, flanges, boat shafts, various applications in the oil & gas, chemical, power and brewing industries.
