UNS S32760 Super Duplex Stainless Steel Seamless High Precision & Heat Exchanger Tubes

Our UNS S32760 Super Duplex Stainless Steel Seamless High Precision & Heat Exchanger Tubes are engineered for the most demanding industrial environments where ultra-high strength, exceptional corrosion resistance, and long-term operational reliability are critical. The super duplex microstructure combines the strength of ferritic stainless steel with the corrosion resistance of austenitic stainless steel, delivering outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich and aggressive chemical environments.

The seamless, high-precision construction ensures uniform wall thickness and ultra-smooth internal surfaces, minimizing pressure loss and maximizing heat transfer efficiency in critical systems. These tubes maintain superior performance under extreme pressure and temperature conditions, making them ideal for heat exchangers, condensers, petrochemical processing, offshore platforms, subsea systems, and marine piping networks.

Widely used across oil & gas, chemical processing, marine, power generation, and heavy industrial sectors, our UNS S32760 seamless tubes undergo rigorous quality control and international standard testing, delivering a durable, high-performance, and cost-effective solution for the harshest service and high-pressure operating conditions.
