Duplex steel ASME A789 /A790 S32205&S31803 U bending tubes ,Pickled and Annealed ,6M/PC for Heat exchanger
Super duplex stainless such as duplex is a mixed microstructure of austenite and ferrite which has improved strength over ferritic and austenitic steel grades . The main difference is super duplex has a higher molybdenum and chromium content which gives the material greater corrosion resistance .
Super duplex has the same benefits as its counterpart - it has lower production costs when compared with similar ferritic and austenitic grades and due to the materials increased tensile and yield strength , in many cases this gives the purchaser the welcomed option of purchasing smaller thicknesses without the need to compromise on quality and performance .
ASTM A789 ASME SA 789 S32205 2205 Duplex Tube is a 22% chromium, 3% molybdenum, 5-6% nickel, nitrogen alloyed duplex stainless steel with high general, localized, and stress corrosion resistance properties in addition to high strength and excellent impact toughness. S32205 is very similar with S31803. The difference is on Chemical composition. Usually we use Grade S32205 replace Grade S31803.
