ASTM A789 S31803 Duplex Stainless Steel Seamless Tube HT/ECT Available

Duplex Stainless Steel Pipes ASTM A789 S31803 19.05*1.65 for Chemical Process Plant

The Duplex Steel Pipe gets its name from the dual nature present in the microstructure of the alloy. Duplex Stainless Steel Seamless Pipe have good mechanical characteristics and can be used in an as welded condition. Considered to be superior in comparison to austenitic alloys ASTM A312 TP304 or ASTM A312 TP316, the Seamless Duplex Pipe offers much better resistance to corrosion.
