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 10216-5Manufacturing Process: Seamless (hot finished / cold drawn)Size Range: ½” to 24” OD (custom sizes on request)Schedules: SCH 10 – SCH XXS
UNS S33207 Seamless Hyper Duplex Steel Tube designed for exceptional strength, corrosion resistance, and toughness, especially in highly aggressive environments. As a seamless pipe, it offers superior structural integrity and uniform properties across the cross-section.Manufacturing Process: Seamless (hot finished / cold drawn)Standards: ASTM A789 / ASME SA789, NORSOK MDS, ISO, EN equivalentsSize Range: ½” to 10” OD (or custom sizes on request)
S32205 Seamless Duplex Steel Pipe, also known as Duplex 2205, is a nitrogen-enhanced duplex stainless steel that offers a superior combination of high strength and excellent corrosion resistance. Seamless pipes and tubes made from this material are widely used in various demanding industrial applications where standard austenitic stainless steels are inadequate. Its balanced chemical composition and microstructure provide a desirable set of properties that make it a cost-effective solution for many corrosive environments,known for their excellent mechanical strength and durability in demanding environments.① STANDARD: ASTM A789/ ASTM A790/ ASTM A928/ ...② OD RANGE : 6-720 MM③ THICKNESS RANGE: 1-65 MM
UNS S32760 Seamless Super Duplex Steel Tube, UNS S32760 is a high-performance super duplex stainless steel highly regarded for its exceptional strength and outstanding corrosion resistance, particularly in aggressive, chloride-containing environments. Seamless pipes made from this material are engineered for critical applications where reliability and longevity are paramount.UNS S32760's primary advantage is its excellent resistance to various forms of corrosion. • Pitting and Crevice Corrosion: This grade boasts a high Pitting Resistance Equivalent Number (PREN), calculated as PREN = %Cr + 3.3(%Mo + 0.5%W) + 16%N. With a PREN value typically exceeding 41, it offers outstanding resistance to localized corrosion in seawater and other chloride-rich media.• Stress Corrosion Cracking (SCC): The duplex structure provides excellent resistance to chloride-induced SCC, a common vulnerability for standard austenitic stainless steels.• Sour Service: It is resistant to sulfide stress cracking in sour gas environments, making it suitable for oil and gas applications.① STANDARD: ASTM A789/ ASTM A790/ ASTM A928/ ...② OD RANGE : 6-720 MM③ THICKNESS RANGE: 1-65 MM
