1.4462 Duplex Stainless Steel Pipe , UNS S31803 20FT Double Tube Heat Exchanger


Features:


Higher strength than standard stainless steels


Higher corrosion resistance than 316 stainless steel in a wide variety of corrosive chemicals including sulphuric, phosphoric and nitric acids


Good resistance to pitting and crevice corrosion in seawater


High stress corrosion resistance


Lower thermal expansion than austenitic stainless steels


Higher thermal conductivity than austenitic stainless steels


Corrosion Resistance:


UNS S31803 is resistant to intergranular corrosion. It has better corrosion resistance than that of other austenitic stainless grades such as 316, with higher resistance to stress corrosion cracking to that of either 304 or 316 stainless grades. Pitting corrosion and crevice corrosion is higher than that of 316. Due to its higher corrosion resistance UNS S31803 has better fatigue strength in corrosive environments than that of other austenitic stainless steel specifications.
