Duplex Ferritic Austenitic Stainless Steel Tube Pipe Seamless - China

Duplex Stainless Steels have a structure that contains both ferrite and

austenite.

Duplex alloys have higher strength and better stress

corrosion cracking resistance than most austenitic alloys and greater

toughness than ferritic alloys, especially at low temperatures.

The

corrosion resistance of duplex alloys depends primarily on their

composition, especially the amount of chromium, molybdenum, and nitrogen

they contain.
