Product Description
UNS S31803, EN 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
