Hastelloy Tube
Premium-grade Hastelloy tubes from Stellanox Steel are designed for demanding applications in harsh chemical, marine, power generation, and high-temperature settings. These tubes are renowned for their exceptional mechanical strength under heat and pressure, as well as their resistance to corrosion and thermal stability.
Our seamless and welded Hastelloy tubes are available in various grades, including Hastelloy C276, C22, B2, and G30. They can be customized in size to fit project requirements in various sectors.
What are Hastelloy Tubes?
Hastelloy tubes are hollow, cylindrical parts composed of alloys based on nickel that are excellent at fending off oxidation, pitting, acid attack, and corrosion in both reducing and oxidising environments. Heat exchangers, condenser coils, evaporators, boiler tubing, and fluid transport systems in extremely corrosive conditions are among the many applications for these tubes.
When stainless steel and other alloys fail in operations involving sulphuric acid, hydrochloric acid, ferric and cupric chlorides, and chlorine dioxide, they are crucial.
