Duplex S31803 U Tubing,ASME SA789 Duplex Stainless Steel U bend Tubes

ASTM A789 ASME SA 789 S32205 Duplex Stainless Steel is a nitrogen enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steel. "Duplex"describes a family of stainless steel that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless steel. The structure of S32205 duplex stainless steel consists of austenitic pools surrounded by a continuous ferritic phase. In the annealing condition, S32205 contains approximately 40-50% ferrite. Often referred to as the work horse grade, 2205 is the most widely used grade in the duplex stainless steel tube.
