Super Duplex Steel S32760 Instrumentation Tubes are precision-engineered tubing products manufactured using a highly alloyed grade of stainless steel. This material, designated as UNS S32760, combines high strength with outstanding corrosion resistance, making it ideal for use in demanding industrial environments. These tubes are specifically designed for carrying instrumentation signals, hydraulic fluids, or chemical injections in systems where reliability, corrosion resistance, and mechanical performance are critical.
S32760 is a super duplex stainless steel, characterized by a two-phase microstructure of austenite and ferrite, which provides it with exceptional strength—nearly twice that of conventional austenitic stainless steels. It contains high levels of chromium (24–26%), molybdenum (3–4%), and nitrogen, along with additions of copper and tungsten. This unique composition results in excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking, even in aggressive environments such as seawater or acidic chemical processing plants.
Super Duplex S32760 Instrumentation Tubes are commonly used in industries such as offshore oil and gas, petrochemicals, chemical processing, desalination, and marine engineering. These tubes are essential for precise transmission of fluid or gas in control systems, instrumentation panels, and chemical injection systems. Their strength and corrosion resistance also make them suitable for high-pressure environments and sour service applications compliant with NACE MR0175 / ISO 15156.
These instrumentation tubes are available in seamless and welded forms, with outer diameters typically ranging from 6 mm to 25.4 mm (1/4" to 1"). They are manufactured to meet stringent international standards such as ASTM A789 and ASTM A790. Tubes can be supplied in straight lengths or coils, and are often cold-worked to ensure high dimensional accuracy, smooth internal surfaces, and consistent mechanical performance under pressure.
