Hastelloy C22 Pipe is a top-notch alloy made from nickel, chromium, molybdenum, and tungsten, celebrated for its remarkable ability to withstand both oxidizing and reducing environments. It provides excellent protection against a variety of chemical substances, such as wet chlorine, acetic acid, formic acid, and strong oxidizers. These pipes are engineered for outstanding mechanical performance in highly corrosive settings, making them a go-to choice for the chemical and petrochemical sectors. With their impressive formability, weldability, and durability, they ensure reliable operation even in tough conditions. Thanks to their high tensile strength and thermal stability, they excel in high-pressure and high-temperature applications that require both corrosion resistance and structural integrity.

Hastelloy C22 Pipes are primarily composed of nickel (56%), chromium (20–22.5%), molybdenum (12.5–14.5%), and tungsten (2.5–3.5%), along with trace amounts of iron, cobalt, and vanadium. This unique blend gives them exceptional resistance to pitting, crevice corrosion, and stress-corrosion cracking. The pipes boast a tensile strength of about 690 MPa, a yield strength of 283 MPa, and an elongation of roughly 45%. They maintain excellent mechanical stability up to 1250°F (677°C). The metallurgical stability of Hastelloy C22 ensures it resists grain-boundary precipitation, even during welding, making it suitable for extreme chemical and thermal environments.
