6 Differences Between Common Stainless Steel Pipe and Duplex Stainless Steel Pipe

1. Composition: Common stainless steel pipes are made of austenitic or ferritic stainless steel, while duplex stainless steel pipes are made of a combination of austenitic and ferritic stainless steel.


2. Corrosion resistance: Duplex stainless steel pipes have higher corrosion resistance than common stainless steel pipes due to their higher chromium and molybdenum content.


3. Strength: Duplex stainless steel pipes have higher strength than common stainless steel pipes due to their duplex microstructure.


4. Weldability: Common stainless steel pipes have better weldability than duplex stainless steel pipes due to their single-phase microstructure.


5. Price: Duplex stainless steel pipes are more expensive than common stainless steel pipes due to their higher alloy content and manufacturing complexity.


6. Applications: Duplex stainless steel pipes are commonly used in industries such as oil and gas, chemical processing, and marine engineering, while common stainless steel pipes are used in a wider range of applications such as construction, food processing, and medical equipment.
