ASTM A789 UNS S32906 duplex stainless steel tubes from Emirerri Steel are premium‑grade duplex stainless steel piping products engineered for high‑performance corrosion resistance, high mechanical strength, and long‑term durability in aggressive environments. These tubes are manufactured to the ASTM A789/A789M specification, covering both seamless and welded duplex stainless steel tubes suitable for demanding industrial applications.
The duplex microstructure (a balanced ferritic–austenitic phase) of UNS S32906 provides significantly higher strength and superior resistance to chloride‑induced pitting, crevice corrosion, and stress‑corrosion cracking compared to conventional austenitic stainless steels, making this grade ideal for use in chemical, marine, and high‑pressure systems.
