Hastelloy® C-22 Small Diameter Tubing

Hastelloy® C-22 Small Diameter Tubing

Advanced Corrosion Resistance for Harsh Chemical Environments — from International Tube

At International Tube, we produce high-performance Hastelloy® C-22 small diameter tubing (UNS N06022), a nickel-chromium-molybdenum-tungsten alloy engineered for exceptional resistance to a wide range of aggressive chemicals and corrosive media. Known for its versatility, Hastelloy C-22 provides superior protection against pitting, crevice corrosion, and stress corrosion cracking, making it one of the most corrosion-resistant alloys available for critical applications.

With a carefully balanced composition—including nickel, chromium, molybdenum, iron, and tungsten—Hastelloy C-22 is especially effective in oxidizing and reducing environments, offering reliable performance in processes involving chlorides, strong acids, and mixed chemical conditions. It remains highly stable even under continuous heat and pressure.

Hastelloy C-22 Tubing Features & Applications

At International Tube, our Hastelloy C-22 tubing is trusted across industries that demand maximum corrosion resistance, cleanliness, and mechanical durability. Typical applications include:

• Chemical processing and reactor systems

• Pharmaceutical and biotech production equipment

• Scrubbers, vents, and gas handling systems

• Marine and offshore platforms exposed to chlorides and salt spray

• Nuclear waste and flue gas desulfurization systems

• Pulp and paper bleaching equipment

• Instrumentation tubing in high-purity chemical environments

Our small-diameter Hastelloy C-22 tubing is manufactured from high-purity alloy strip stock, plug drawn in coil form, and annealed as needed to meet specified mechanical and temper requirements. Tubing is available in both straight lengths and continuous coil form, offering maximum flexibility for complex assemblies and corrosion-critical installations.

For applications where chemical resistance, reliability, and material integrity are non-negotiable, International Tube delivers Hastelloy® C-22 tubing built for performance in the most demanding environments.
