ATSM A790 Duplex Stainless Steel Pipe S32760 used in the chemical and process industries
Product Discription:
Alloy 32760 is a super duplex stainless steel supplied under hot working and solid solution annealing conditions. As a super duplex stainless steel, it combines the advantages of both austenite and ferrite. The higher chromium, molybdenum and nitrogen content results in a pitting resistance equivalent number (PREN) of 40, providing better pitting and crevice corrosion than austenitic and duplex stainless steels in almost all corrosive media. The local corrosion resistance of super duplex stainless steel is close to 6% Mo super austenite grade. It has high strength and excellent corrosion resistance in many environments and is used in the chemical and process industries.
Features:
- Excellent corrosion resistance in a wide variety of corrosive chemicals
- Pitting Resistance Equivalent number (PREN) of >40
- Outstanding resistance to pitting and crevice corrosion in seawater and other chloride containing environments
- Critical Pitting Temperature exceeding 50°C
- High strength compared to austenitic and 22%Cr duplex stainless steels
- Excellent ductility and impact strength at both ambient and sub-zero temperatures
- High resistance to abrasion, erosion and cavitation erosion
- Excellent resistance to stress corrosion cracking in chloride containing environments
- Listed in NACE MR 0175 for sour service
- ASME Approval for Pressure Vessel application
