Hastelloy Tube
Stellanox Steel offers premium-quality Hastelloy Tubes engineered for critical service in aggressive chemical, marine, power generation, and high-temperature environments. These tubes are known for their outstanding corrosion resistance, thermal stability, and mechanical strength under pressure and heat.
Available in grades like Hastelloy C276, C22, B2, and G30, our Hastelloy tubes are available in seamless and welded options, with custom dimensions to meet project specifications across a wide range of industries.
What are Hastelloy Tubes?
Hastelloy Tubes are hollow cylindrical components made from nickel-based alloys that excel in resisting acid attack, pitting, crevice corrosion, and oxidation in both oxidizing and reducing media. These tubes are widely used for heat exchangers, condenser coils, evaporators, boiler tubing, and fluid transport systems in highly corrosive environments.
They are essential in processes involving sulfuric acid, hydrochloric acid, ferric and cupric chlorides, and chlorine dioxide, where stainless steel and other alloys fail.
