S31803 (DUPLEX)

Place of Origin: South Korea



S31803 is a duplex stainless steel

S31803 is a duplex stainless steel designed to combine improved resistance to stress corrosion cracking, pitting, crevice corrosion and high strength in comparrison with other stainless alloys.





31803 Duplex alloy resists chloride environments and sulphide stress corrosion. Duplex 31803 is?also roughly double the strength of standard austenitic stainless steel grades.





31803 Duplex can be used successfully as?an alternative to standard stainless steel in applications where higher strength and resistance to stress corrosion cracking is required. 31803 Duplex is also referred to as 2205.
