Hastelloy C22 Plates and Sheets | ASTM B575 UNS N06022 Supplier India
Hastelloy C22 Plates and Sheets (ASTM B575 / UNS N06022) are premium nickel-chromium-molybdenum-tungsten flat products engineered for superior resistance to oxidizing acids, chloride-induced pitting, and stress corrosion cracking in the most aggressive process environments.
Jade Alloys, Mumbai, maintains a ready stock of Hastelloy C22 Sheets, Plates, Coils, Shims, Strips, and Foils and supplies to buyers across India, the Middle East, Europe, and Southeast Asia. We are a trusted Hastelloy C22 Plates and Sheets manufacturer and supplier operating from Mumbai for many years, serving the chemical, oil and gas, pharmaceutical, and power generation industries.
Hastelloy C22 is a versatile nickel-chromium-molybdenum-tungsten alloy that provides outstanding resistance to a wide array of corrosive media. This includes oxidizing acids with chloride ions, nitric acid mixtures, and wet chlorine. The ASTM B575 standard specifies requirements for low-carbon nickel-based alloys in sheet, plate, and strip forms. Our Alloy C22 Plate products fully comply with these standards, ensuring they meet the necessary chemical and mechanical properties such as tensile strength and hardness.
The alloy’s rich composition makes it highly resistant to corrosion in both flowing and stagnant water, making Hastelloy C22 Sheets and Hastelloy C22 Plates ideal for high-performance, high-temperature applications. It is also highly ductile and easy to weld due to its low carbon content, which prevents the formation of grain-boundary precipitates. This means it can be used in its as-welded state without the need for additional heat treatment. Hastelloy C22 is a preferred material for many industrial components, including reactors, heat exchangers, and columns in the chemical process industry. Its superior resistance to both oxidizing and non-oxidizing chemicals, as well as pitting and stress corrosion cracking, makes it a reliable choice for critical applications.
We supply both Hot Rolled (HR) and Cold Rolled (CR) forms of these sheets and plates. Our products are available in various forms, including coils, foils, and strips, and can be customized to fit specific project requirements. As a reliable exporter of ASTM B575 Alloy C22 from Mumbai, we offer competitive pricing. All material is supplied with EN 10204 3.1 Mill Test Certificates traceable to ASTM B575 requirements. Jade Alloys is exported to 50 or more countries including Saudi Arabia, UAE, Europe, USA, and Singapore.

Applications of Hastelloy C22 Sheets and Plates
Hastelloy C22 Sheets and Plates maintain excellent mechanical integrity up to 677 deg C (1250 deg F) in continuous service. Exposure beyond this limit causes detrimental phase precipitation. For intermittent service, the alloy performs reliably up to 1093 deg C (2000 deg F). The alloy is used across the following industries:
|
|
Hastelloy C22 Plates are specifically used in flue gas desulfurization (FGD) scrubbers, pharmaceutical reactor linings, and chlorine handling systems where C276 performance is insufficient. The alloy’s tungsten content provides superior resistance in mixed-acid environments. It has also been used successfully as scrubber components for hospital waste, municipal waste, and spent solvent incineration, as well as in waste-water treatment ion exchange resin rejuvenation systems.
Welding and Fabrication of Hastelloy C22 Sheets and Plates
Hastelloy C22 can be welded using GTAW (TIG), GMAW (MIG), SMAW (stick), SAW, and plasma welding processes. The recommended filler metal is ERNiCrMo-10 (AWS A5.11 ENiCrMo-10), which is a matching C22 filler. No post-weld heat treatment is required due to the alloy’s low carbon content, which prevents grain-boundary carbide precipitation. Avoid welding in the 600 to 1100 deg C range to prevent sensitisation.
Available fabrication processes include edging, deburring, grinding, waterjet cutting, laser cutting, plasma cutting, and oxy-propane flame cutting. Value-added services include cutting to length, polishing, sawing, shearing, bending, blanking, and slitting.
| Welding Process | Notes |
|---|---|
| GTAW (TIG) | Recommended for precision welds and thin sheets |
| GMAW (MIG) | Suitable for automated welding of plates |
| SMAW (Stick) | General purpose, suitable for field welding |
| SAW | Submerged arc welding for heavy plates |
| Filler Metal | ERNiCrMo-10 (Hastelloy C22 matching filler) |
| Post-Weld Heat Treatment | Not required |
| Welding Electrode | AWS A5.11 ENiCrMo-10 |
Hastelloy C22 vs C276: Which to Choose?
Both Hastelloy C22 and C276 are nickel-chromium-molybdenum alloys covered under ASTM B575, but they differ in composition and performance in specific environments. Use this table to select the right grade for your application:
| Property | Hastelloy C22 (UNS N06022) | Hastelloy C276 (UNS N10276) |
|---|---|---|
| Oxidizing acid resistance | Superior | Good |
| Reducing acid resistance | Good | Superior |
| Chlorine SCC resistance | Superior | Good |
| Chloride-induced pitting resistance | Superior | Good |
| Tungsten content | Yes (2.50 to 3.50%) | No |
| Mixed-acid environments | Superior | Good |
| Weldability | Excellent (as-welded use) | Excellent |
| ASTM Standard | B575 | B575 |
For mixed-acid and chlorinated environments, Hastelloy C22 is typically the better choice. For a broader range of reducing conditions, C276 is preferred. Contact Jade Alloys for a technical recommendation based on your specific application and corrosive media.
