Super Duplex Steel S32760 Capillary Tubes are engineered for applications requiring high strength and exceptional corrosion resistance. This grade, also known as UNS S32760, is a super duplex stainless steel containing a balanced mixture of austenitic and ferritic phases. The alloy composition—typically including 25% chromium, 7% nickel, 3.6% molybdenum, along with additions of tungsten and nitrogen—provides enhanced resistance to localized corrosion such as pitting and crevice corrosion, particularly in chloride-rich environments.
These capillary tubes are widely used in industries such as oil & gas, petrochemicals, marine engineering, and desalination due to their high resistance to stress corrosion cracking and fatigue. In offshore drilling operations, where materials are exposed to highly corrosive seawater and extreme pressures, S32760 capillary tubes offer longevity and reliability. Their superior performance under both static and dynamic load conditions makes them ideal for control line tubing, chemical injection lines, and instrumentation.
The precision with which these capillary tubes are manufactured ensures tight tolerances, smooth internal surfaces, and consistent dimensional accuracy. This is particularly critical for applications where fluid transfer or measurement accuracy is essential, such as in analytical instrumentation or hydraulic systems. Their small diameter and thin walls allow for efficient fluid flow while maintaining high mechanical strength, which is a unique advantage over many conventional stainless steels.
Another key benefit of Super Duplex S32760 is its excellent weldability and workability. Although its high strength can make it more challenging to machine compared to standard stainless steels, it can still be fabricated and welded using appropriate techniques and filler materials. Post-weld heat treatment is generally not required, and the mechanical properties remain stable, even after fabrication. This makes the material suitable for custom tube assemblies and complex system integration.

In terms of corrosion resistance, S32760 capillary tubes outperform many stainless steels, particularly in aggressive environments where chloride concentrations are high. The presence of molybdenum and nitrogen enhances resistance to pitting and crevice corrosion, while the ferritic phase contributes to its superior stress corrosion resistance. These properties are particularly beneficial in subsea systems, heat exchangers, and chemical injection systems where exposure to corrosive substances is constant.
