UNS S31803

S31803 is a nitrogen enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels. “Duplex” describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless. Often referred to as the work horse grade, 2205 is the most widely used grade in the duplex family of stainless steels.
2.1 The characteristics of S31803:

High general corrosion resistance
Pitting and crevice corrosion resistance superior to 317L austenitic stainless steel
Rintangan tinggi terhadap keretakan kakisan tekanan klorida
High resistance to corrosion fatigue and erosion
Good sulfide stress corrosion resistance
Kekuatan tinggi
Excellent impact toughness
Lower thermal expansion and high thermal conductivity than austenitic stainless steels
Good workability and weldability

2.2 The applications of Duplex S31803:

Kapal proses kimia, paip dan penukar haba
Penggali kilang pulpa, pencuci peluntur, bekas cawangan pra-mangkuk
Peralatan pemprosesan makanan
Pemasangan medan minyak dan penukar haba
Peralatan api desulfurization gas
Effluent scrubbing systems
Rotors, fans, shafts, and press rolls requiring combined strength and corrosion resistance
Cargo tanks for ships and trucks
