FeedbackStainless Steel and Duplex Pipe (ASTM A312, A790 High Corrosion Resistance 316 duplex welded stainless steel pipe

Duplex stainless steel shows a superior corrosion resistance to grade 316 for most applications (excellent resistance to localized corrosion including intergranular, pitting and crevice corrosion; the CPT of 2205 is generally at least 35ºC). Duplex is also resistant to chloride corrosion cracking (SCC) at temperatures up to about 150ºC. What are the mechanical properties of duplex steel?What are the mechanical properties of duplex steel?The mechanical properties of Duplex steels are approximately double those of singular austenitic steels, and resistance to stress corrosion cracking is far superior to type 316 stainless steel in chloride solutions.Duplex and Super Duplex - Special Piping Materials What is a duplex stainless steel?What is a duplex stainless steel?Duplex. Duplex steels have improved strength over austenitic stainless steels and improved resistance to localised corrosion, particularly pitting, crevice corrosion and stress corrosion cracking. They are characterised by high chromium (1928%) and molybdenum (up to 5%) and lower nickel contents than austenitic stainless steels.Duplex and Super Duplex Stainless Steels Special Piping Materials
