Duplex Stainless Steel Pipe

Introduction of Duplex stainless steel pipe

The unique feature of Duplex stainless steel pipes lies in the fact that the ferrite and austenite phases each account for half of their microstructure. This special microstructure gives duplex stainless steel pipes excellent corrosion resistance and high strength, while maintaining good plasticity and toughness. In addition, the continuous use temperature range of Duplex stainless steel pipes is -50℃~250℃, and rapid cooling is required after solution treatment to avoid the precipitation of brittle phases and maintain the toughness of steel.
