Duplex UNS- S31803

UNS S31803, F51, 1.4462 duplex stainless steel is designed to combine improved resistance to stress corrosion cracking, pitting, crevice corrosion and high strength when compared with other stainless alloys. Duplex UNS S31803, F51, 1.4462duplex alloy resists chloride environments and sulphide stress corrosion. Duplex UNS S31803, F51, 1.4462 is also roughly double the strength of standard austenitic stainless steels. These attributes mean that Duplex UNS S31803, F51, 1.4462 can be used successfully as an alternative to standard stainless steel specifications in applications where higher strength and resistance to stress corrosion cracking is required.  Duplex UNS S31803, F51, 1.4462 is also referred to as 2205. When machining UNS S31803, F51, 1.4462 turning feeds above 0.25mm are recommended whenever possible and SNMG120408 carbide tools are advised for optimum chip breaking of this duplex stainless steel specification. For drilling ofUNS S31803, F51, 1.4462, high pressure lubrication is recommended and coated carbide tools are preferred.
