Product Description
Hastelloy C22 Seamless Nickel Alloy Tube
ASTM B622 Seamless Round Tube made from advanced nickel-chromium-molybdenum-tungsten alloy for superior corrosion resistance in aggressive industrial environments.
Product Overview
Alloy C22 is an enhanced nickel-chromium-molybdenum-tungsten alloy designed for exceptional performance in corrosive industrial applications. This improved formulation offers excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking in both oxidizing and acid chloride environments.
Key Advantages
- Superior overall corrosion resistance compared to Alloy C-276
- Outstanding resistance to chloride pitting, crevice corrosion, and stress corrosion cracking
- Excellent performance in oxidizing aqueous environments including wet chlorine and nitric acid mixtures with chloride ions
- Superior weldability with alloy C22 weld fillers used for joining other corrosion-resistant alloys
- Excellent resistance to seawater corrosion under both stagnant and flowing conditions

Fabrication Guidelines
Although ductile enough for cold working, intermediate annealing may be necessary due to work hardening. Forging should be performed between 1750-2050°F followed by rapid cooling. Annealing can be performed at 2020-2150°F followed by rapid quench to avoid detrimental phase formation between 1400-1800°F. Welding can be done by gas tungsten-arc, gas metal-arc and shielded metal-arc processes.
