Our Hastelloy C22 plates and sheets are also available in any thickness between 0.1mm and 100mm and with a width of up to 2000mm, which are used in chemical processing, petrochemical plant, flue-gas desulfurization, pollution controls, pharmaceutical and marine engineering. To customers who seek alloy substitutes to very aggressive media, we also offer superior Hastelloy C276 plates which offer improved corrosion performance of the plates in harsh working environments.
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 use in fabricated process equipment, heat exchanger, reactor vessel 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 system and flue-gas desulfurization units. Hastelloy C22 plates and sheets have a balanced mechanical life, corrosion life and ease of fabrication that makes them better services in long-term use in highly corrosive operating conditions.
Technical Specifications of Hastelloy C22 Plates and Sheets
The Hastelloy C22 plates and sheets have specifications that determine their suitability in the challenging corrosion-resistant applications in chemical processing, marine applications, and in high-temperature applications. These are manufactured under the standards of both ASTM B575 and UNS N06022 grades, and are available in a variety of finishes, sizes and hardness to suit varied fabrication, machining and performance needs.

Frequently Asked Questions About Hastelloy C22 Plates And Sheets
Hastelloy C22 is a nickel-chromium-molybdenum alloy that is developed to have exceptional pitting, crevice corrosion and stress-corrosion cracking resistance in arduous, chemical-challenging conditions. It is applied in equipment dealing with chlorides, oxidising acids and high process media.
Hastelloy C22 plates and sheets are utilized in chemical processing, pollution control devices, marine engineering, pharmaceuticals, high temperature equipment and apparatus that is subjected to strong acids, chlorides and oxidising agents.
The two alloys are excellent in corrosion resistance, though Hastelloy C22 is superior in resisting localised corrosion in an oxidising and chloride-laden environment. C276 has a great performance in terms of media and high temperature.
No. Hastelloy is a nickel-based superalloy which is more resistant to corrosion than stainless steel. It has improved performance in harsh chemical conditions such as stainless steel can suffer as a result of pitting or stress-corrosion cracking.
Hastelloy C22 Plates and sheets are produced to ASTM B575 / ASME SB575, and the grades are UNS N06022 and WNR 2.4602. These norms guarantee the accuracy of chemicals, mechanical strength and surface integrity.
Hot rolled (HR), Cold Rolled (CR), 2B, 2D, BA, Satin, Polished, and Bright Annealed are also used and appropriate finishes in fabricating, machining, heat-resistant components and precision parts.
Yes. Hastelloy C22 has very high weldability capabilities with GTAW, GMAW or SMAW. It has a low level of carbon, which prevents the formation of carbide and also ensures corrosion resistance to weld spots.
