Manufacturers and suppliers of UNS S32205 Duplex 2205 Stainless Steel Seamless High Precision & Heat Exchanger Tubes, engineered for offshore, marine, chemical processing, reliable performance in high-pressure and chloride-rich service environments.
Our UNS S32205 Duplex 2205 Stainless Steel Seamless High Precision & Heat Exchanger Tubes
are engineered for severe industrial environments where exceptional mechanical
strength, superior corrosion resistance, and long-term operational reliability
are critical. Featuring a balanced duplex microstructure of approximately equal
parts ferrite and austenite, these tubes deliver nearly twice the yield strength
of conventional austenitic stainless steels while maintaining excellent toughness
and formability.
Duplex 2205 offers outstanding resistance to pitting, crevice corrosion, and
stress corrosion cracking (SCC), particularly in chloride-rich and marine
environments. The seamless, high-precision construction ensures uniform wall
thickness and ultra-smooth internal surfaces, reducing pressure drop and
maximizing heat transfer efficiency in demanding thermal and fluid handling systems.
Widely used in offshore oil & gas, chemical processing, desalination, marine
engineering, power generation, and high-pressure heat exchanger systems, our
UNS S32205 tubes are manufactured and tested to stringent international standards,
delivering a durable, high-performance, and cost-effective solution for aggressive
and high-load service conditions.

Our global footprint reflects the trust industries place in our ability to supply high-strength, corrosion-resistant, and high-performance tube solutions for the world’s most demanding environments.
Precision seamless manufacturing ensures uniform wall thickness, tight dimensional tolerances, and smooth internal surfaces for optimized fluid flow, reduced pressure loss, and enhanced heat transfer efficiency.
High chromium, molybdenum, and nitrogen content provides superior resistance to pitting, crevice corrosion, and general corrosion in chloride-rich, marine, and aggressive chemical environments.
Duplex microstructure delivers nearly twice the yield strength of conventional austenitic stainless steels, enabling thinner wall designs and safe operation under high-pressure and heavy-load service conditions.
Excellent resistance to chloride-induced stress corrosion cracking (SCC), making these tubes ideal for offshore, desalination, heat exchanger, and chemical processing applications.
Maintains structural stability and mechanical performance across a wide temperature and pressure range, ensuring consistent service in heat exchangers, condensers, and energy systems.
High strength and corrosion resistance reduce maintenance requirements and extend operational lifespan, lowering total lifecycle costs in continuous-duty and harsh operating environments.
UNS S31803 Duplex Stainless Steel Seamless Tubes are produced using hot extrusion and cold drawing followed by solution annealing and controlled quenching. The balanced duplex microstructure provides high mechanical strength and exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, making these tubes ideal for offshore, marine, chemical processing, oil & gas, and high-pressure heat transfer applications.
Each tube undergoes comprehensive inspection including Eddy Current Testing (ECT), Hydrostatic Pressure Testing, Positive Material Identification (PMI), dimensional and visual inspection, chemical analysis, and ferrite / phase balance verification to ensure structural integrity, alloy conformity, and reliable performance in critical service environments.
Manufactured in accordance with ASTM A789 / A790, ASME SA789 / SA790, EN 10216-5, ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and PED 2014/68/EU.
