ASTM A790 S31260 Stainless Steel Tube For Chemical Plants
Specifications
ASTM A790 covers seamless and straight-seam welded ferritic/austenitic stainless steel pipe intended for general-purpose applications.
ASTM A790 S31260 is a standard for duplex stainless steel seamless and welded pipes made from the UNS S31260 grade, which combines high strength with excellent corrosion resistance, particularly in chloride and high-temperature environments. These pipes are used in demanding applications like chemical plants, seawater systems, and high-pressure equipment due to their resistance to pitting, crevice corrosion, and stress corrosion cracking.
