ASTM A790 UNS S32760 Stainless Steel Tube For Chemical And Process Industry
Specifications
ASTM A790 covers seamless and straight-seam welded ferritic/austenitic stainless steel pipe intended for general-purpose applications.
ASTM A790 UNS S32760 is a super duplex stainless steel pipe specification for both seamless and welded pipes, valued for its high strength and excellent corrosion resistance, particularly against chloride pitting. This material is frequently used in demanding applications like chemical processing, offshore oil and gas equipment, and desalination plants, where it offers superior durability and performance compared to standard stainless steels. It is a combination of austenitic and ferritic stainless steels, with high chromium, molybdenum, and nitrogen content.
