UNS N06625 Nickel Alloy Seamless Tubes

Our UNS N06625 Nickel Alloy Seamless Tubes (Inconel 625) are engineered to deliver exceptional performance in the most demanding and corrosive environments. Manufactured from a high-strength nickel–chromium–molybdenum alloy with niobium addition, these tubes provide outstanding resistance to oxidation, pitting, crevice corrosion, and stress corrosion cracking.

The seamless construction ensures a smooth internal surface, reducing pressure drops and improving flow efficiency in critical systems. UNS N06625 seamless tubes retain excellent mechanical strength across a wide temperature range without requiring precipitation hardening, making them ideal for heat exchangers, condensers, offshore piping, and high-pressure process equipment.

Widely used in chemical processing, aerospace, oil & gas, marine, offshore, and power generation industries, our UNS N06625 nickel alloy seamless tubes undergo rigorous quality control and testing to meet international performance standards. They provide a reliable, long-lasting, and cost-effective solution for applications exposed to extreme corrosion, pressure, and thermal stress.
