Ojas Pipes and Tubes stands out as a top-notch manufacturer and supplier of premium Hastelloy C22 Tubing, proudly based in Kolkata, India. Crafted from the advanced nickel-chromium-molybdenum alloy UNS N06022, this tubing boasts remarkable resistance to a variety of corrosive environments, whether they’re oxidizing or reducing. Renowned for its exceptional defense against pitting, crevice corrosion, and stress corrosion cracking, Hastelloy C22 tubing is perfect for critical applications in industries like chemical processing, pharmaceuticals, marine, and pollution control. Ojas ensures precision-engineered tubing with outstanding weldability, dimensional accuracy, and surface finish, all in line with international standards such as ASTM B622 and B619.
Hastelloy C22 Tubing is made up of about 56% Nickel, 20–22.5% Chromium, 12.5–14.5% Molybdenum, and 2–6% Iron, along with trace elements of Tungsten, Cobalt, and others. This distinctive blend grants it the ability to resist a wide range of harsh chemicals. The tubing showcases a tensile strength of 690–760 MPa, a yield strength of 310–350 MPa, and an elongation of roughly 45%. It maintains excellent mechanical integrity across a broad temperature spectrum and under extreme corrosive conditions. Additionally, Hastelloy C22 tubing is known for its superb formability and weldability, making it a great fit for complex, high-pressure process systems.
