UNS S32304/Duplex Alloy 2304/1.4362 Seamless Duplex Steel Pipe

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.
As a seamless pipe, it delivers excellent uniformity, pressure resistance, and mechanical integrity.

Standards: ASTM A789 / ASTM A790, ASME SA789 / SA790, EN 10216-5

Manufacturing Process: Seamless (hot finished / cold drawn)

Size Range: ½” to 24” OD (custom sizes on request)
