| High Light | ASTM A789 S32750 stainless steel tube ，Super duplex steel tube high corrosion ，Seamless welded tube high pressure | ||
ASTM A789 S32750 (UNS S32750, commonly known as F53) super duplex stainless steel tube, a ferritic-austenitic dual-phase structure material, is compliant with ASTM A789 standard for general service duplex stainless steel tubing. It is characterized by high strength, excellent chloride corrosion resistance and anti-intergranular corrosion, serving as an important bridge between ordinary duplex steel and nickel-based alloys, widely used in harsh industrial environments such as offshore, petrochemical and desalination.
