Hastelloy C22 Plates and Sheets | ASTM B575 UNS N06022 Supplier Mumbai, India
Jade Alloys has been supplying Hastelloy C22 Sheets and Plates from Mumbai for years now, and we stock the full range: hot-rolled plates, cold-rolled sheets, coils, strips, foils, shim sheets, in thicknesses from 0.3 mm right up to 120 mm. Every piece we ship carries an EN 10204 3.1 Mill Test Certificate fully traceable to ASTM B575 / UNS N06022 (Werkstoff Nr. 2.4602). No exceptions.
C22 is not a general-purpose alloy. It was built for environments that eat through stainless steel and even C276: oxidizing acid service, wet chlorine, nitric acid mixtures, media with chloride ions that cause pitting and crevice attack. What makes it work is the composition: 20 to 22.5% chromium, 12.5 to 14.5% molybdenum, and crucially 2.5 to 3.5% tungsten, which C276 does not have. That tungsten addition is what pushes C22 ahead in mixed-acid and chlorinated environments. The low carbon keeps it clean at the grain boundaries, so you can weld it and put it straight into service with no post-weld heat treatment needed. Continuous service goes to 677°C (1250°F) and intermittent up to 1093°C (2000°F). It holds up in reactor linings, FGD scrubbers, heat exchangers, pharmaceutical vessels, chlorine handling systems, anywhere the process chemistry is genuinely aggressive.
We buy directly from Haynes International, VDM Metals, Special Metals and Thyssenkrupp, which keeps our pricing sharp and our material fully traceable back to the mill. From our Mumbai warehouse, standard orders go out within 3 working days. We export regularly to Saudi Arabia, UAE, Germany, the USA, Singapore and 45+ other countries, so export documentation including Certificate of Origin, Form E and fumigation certificates is something we handle routinely. Cut-to-size, custom thicknesses, non-standard widths: talk to us and we will tell you straight whether we have it or how fast we can get it.

Welding & Fabrication of Hastelloy C22 Sheets & 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), a matching C22 filler. No post-weld heat treatment (PWHT) is required due to the alloy’s low carbon content, which prevents grain-boundary carbide precipitation. Welding procedures for Hastelloy C22 can be qualified per ASME Section IX. No PWHT required per ASTM B575 Annex A. Avoid welding in the 600–1100 °C range to prevent sensitisation.
| 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 (as-welded use permitted) |
| Welding Electrode | AWS A5.11 ENiCrMo-10 |
| ASME Qualification | Per ASME Section IX |
Available fabrication services: Edging, deburring, grinding, waterjet cutting, laser cutting, plasma cutting, oxy-propane flame cutting, cutting to length, polishing, sawing, shearing, bending, blanking, and slitting.

Hastelloy C22 vs C276 — Which to Choose?
Both Hastelloy C22 and C276 are nickel-chromium-molybdenum alloys covered under ASTM B575, but differ in composition and performance. Use this table to select the right grade:
| 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 pitting resistance | Superior | Good |
| Tungsten content | Yes (2.50–3.50%) | No |
| Mixed-acid environments | Superior | Good |
| Weldability | Excellent (as-welded) | 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.
