ASTM A790 UNS S32304 Stainless Steel Tube For Potable Water Distribution Systems
Specifications
ASTM A790 covers seamless and straight-seam welded ferritic/austenitic stainless steel pipe intended for general-purpose applications.
ASTM A790 UNS S32304 Seamless Duplex Steel Pipe,UNS S32304 also called Duplex 2304 or 1.4362 is a lean duplex stainless steel with a balanced austenite + ferrite microstructure. It provides higher strength than 304/316 austenitic stainless steels while maintaining good resistance to general corrosion, pitting, and stress corrosion cracking—at a more cost-effective alloying content.
