ASTM A790 S31803 F51 Duplex Stainless Steel Seamless Pipes For Petrochemical Equipment

ASTM A790 S31803 F51 Duplex Stainless Steel Seamless Pipes For Petrochemical Equipment

YUHONG Group, a Chinese manufacturer that offers duplex stainless steel pipes in more than 80 countries up to now.The products we provide are all of high quality, and our quality inspectors will conduct quality inspections on the goods after production is completed.
 

ASTM A790/ ASME SA790 This specification covers seamless and straight-seam welded ferritic/austenitic steel pipe intended for general corrosive service, with particular emphasis on resistance to stress corrosion cracking. These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures.

Advantages

1. Offers excellent resistance to corrosion, especially in harsh environments such as high chloride and acidic conditions.

2. Have a higher strength compared to austenitic stainless steel pipes, making them suitable for applications that require high mechanical strength.

3. More affordable compared to other high-performance alloys while still providing excellent corrosion resistance and strength.
