Hastelloy C22 Plates and Sheets
Hastelloy C22 plates and sheets are high-performance nickel-chromium-molybdenum alloys that are designed to be used in environments where there are chlorides, oxidizing acids, wet chlorine, and aggressive chemicals. These Alloy C22 plates, sheets, and coils are manufactured according to ASTM B575 and provide high pitting, crevice corrosion, and stress-corrosion cracking resistance and are therefore suitable in harsh industrial environments.
We have hot-rolled Hastelloy C22 plates and sheets, cold-rolled C22 sheets, 2.4602-grade sheets, and 2.4602-grade shim stock and strips in precision form, which are used in chemical processing, offshore equipment, marine engineering, and high-temperature service. All the sheets and plates are made of low-carbon Nickel Alloy C22 (UNS N06022) to promote a high level of corrosion performance, dimensional precision, and welding security.
Available in a thickness of 0.1 mm to 100 mm and a width of 2000 mm, our range of Hastelloy C22 sheet and plate is supplied in a 2B, 2D, HR, CR, and satin finish to cater to a wide variety of project requirements for fabricating, machining, and pressure-rated parts.

What Are Hastelloy C22 Plates and Sheets?
The Hastelloy C22 plates and sheets are nickel-chromium-molybdenum alloys that are high-performance alloys that are meant to provide superior corrosion properties in the harsh industrial conditions. Made to ASTM B575, with UNS N06022 / WNR 2.4602 grade material, they offer excellent resistance to pitting, crevice corrosion and stress-corrosion cracking in chloride-saturated and oxidising chemical environments. The low carbon content of the alloy gives it a high weldability, hence its use in fabricated process equipment, heat exchangers, reactor vessels and pollution-control components.
These plates and sheets come in hot-rolled and cold-rolled finishes, as well as precision C22 shim sheets with any high level of dimension control it is needed. Their robustness and stability enable sound working at hot temperature chemical processing, pharmaceuticals, petrochemicals, offshore systems and flue-gas desulfurisation units. Hastelloy C22 plates and Hastelloy C22 sheets have a balanced mechanical life, corrosion life and ease of fabrication that make them better for long-term use in highly corrosive operating conditions.
