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.

ASTM A789 UNS S39274 Super Duplex Stainless Steel Tubes are high-performance, corrosion-resistant tubular products engineered for demanding environments. Made from UNS S39274, a super duplex stainless steel grade with a balanced ferritic-austenitic microstructure, these tubes offer exceptional strength, high chlorine and pitting corrosion resistance, and excellent mechanical performance.

Super duplex grade S39274 delivers superior resistance to stress-corrosion cracking, crevice corrosion, and general corrosion in chloride-rich and harsh industrial environments. ASTM A789 specifies both seamless and welded duplex stainless steel tubing, making it suitable for use across marine, petrochemical, chemical processing, and power generation sectors.

These tubes are often supplied in solution-annealed and pickled condition to ensure optimal corrosion resistance and surface finish. They are available in various sizes, wall thicknesses, and finishes to meet specific engineering and fabrication requirements.

ASTM A789 UNS S32001 refers to a lean duplex stainless steel grade manufactured as seamless and welded tubes under the ASTM A789 / ASME SA789 specification. Lean duplex stainless steels like UNS S32001 combine the best attributes of both austenitic and ferritic microstructures, delivering higher strength and enhanced corrosion resistance compared with standard austenitic grades such as 304L and 316L.

UNS S32001 tubes are solution annealed and typically finished with pickling, annealing, or polishing to provide superior surface quality. These tubes are designed to perform reliably in aggressive and moderately corrosive environments, offering improved pitting and crevice corrosion resistance, as well as resistance to chloride stress-corrosion cracking—making them well-suited for demanding industrial and structural applications.
