What is the Chemical Composition of Hastelloy C22?
Hastelloy C22 is primarily a nickel-based corrosion-resistant alloy. Its nominal composition includes approximately 56% nickel, 22% chromium, 13% molybdenum and 3% tungsten, with iron, cobalt, manganese, silicon, vanadium, carbon, and other elements controlled at specified levels.
ASTM B575 standard establishes chemical requirements for UNS N06022 plate, sheet and strip, along with requirements covering mechanical properties and product dimensions.
This chemistry is not simply a specification-sheet exercise. Hence we at Nickel Alloy Plate Hub believe that every major alloying element of the Hastelloy C22 (UNS N06022) we offer your business contributes to the material’s performance.They are mentioned below:
- Nickel provides the fundamental corrosion-resistant matrix.
- Chromium contributes strongly to resistance in oxidizing environments and chloride-induced localized corrosion.
- Molybdenum improves resistance to reducing acids, pitting and crevice corrosion.
- Tungsten contributes to corrosion resistance in aggressive environments.
- Low carbon content helps support resistance to sensitization and intergranular corrosion under appropriate processing conditions.
This combination is one reason C22 has become an important material for aggressive chemical environments.
Why Does Chemical Composition Matter in 2026?
The simple answer is application reliability.
Imagine you are purchasing a Hastelloy C22 plate for a chemical-processing component from us at Nickel Plate Alloy Hub. Two materials may appear similar on paper, but small differences in chemistry, manufacturing route, heat treatment, and certification can influence whether the material performs as expected.
In 2026, industries are increasingly focused on lifecycle cost rather than simply the initial purchase price. A material that provides dependable corrosion resistance can potentially reduce maintenance, replacement, and unplanned downtime.
For this reason, when evaluating an UNS N06022 plate supplier, we advice that you should look beyond the quoted Hastelloy C22 plate price and ask us for the appropriate material documentation, specification compliance, and chemical analysis.

For someone searching for Hastelloy C22 plate suppliers in India like us at Nickel Alloy Plate Hub these considerations are particularly important because supplier selection should involve technical documentation as well as commercial comparison.Download our Nickel Alloy Plate Hub Hastelloy C22 (UNS N06022) Technical Specifications PDF.
Where is Hastelloy C22 Used?
Hastelloy C22 is used in demanding corrosion-resistant applications, particularly in the chemical process industry. We identify applications that need it, which includes reactors, heat exchangers, and columns.
The alloy can be supplied in several product forms, including plate, sheet, strip, bar, wire, pipe, and tube.
If you are seeking a Leading Hastelloy C22 plate stockist in Mumbai like us at Nickel Alloy Plate Hub, for example, your evaluation should include more than local availability. Ask whether the stockist can provide the required specification, dimensions, heat/lot traceability, and inspection documentation.
When Should You Check the Chemical Composition?
The best time is before purchasing the material, not after receiving it.
If your specification calls for Hastelloy C22 plate ASTM B575, confirm that the offered material complies with the relevant requirements. ASTM B575 specifically covers plate, sheet and strip made from low-carbon nickel-chromium-molybdenum alloys including UNS N06022.
It is also important to distinguish between product forms. ASTM documentation identifies sheet and strip as products that can be hot or cold rolled, solution annealed and descaled under the specification.
Therefore, when comparing Hastelloy C22 hot rolled plate with Hastelloy C22 cold rolled sheet, don’t focus solely on the words “hot rolled” or “cold rolled.” Confirm the required dimensions, condition, finish, mechanical properties and intended application.
Similarly, we at Nickel Alloy Plate Hub believe that the Hastelloy C22 plate thickness chart should be treated as a dimensional planning tool rather than a substitute for the applicable material specification and supplier documentation.
How Does Chemistry Influence Hastelloy C22 vs C276 Plate Selection?
One of the most common questions is Hastelloy C22 vs C276 plate — which one should you select?
The answer depends on the actual service environment rather than the alloy name alone.
According to our team of experts, C22 has approximately 22% chromium, 13% molybdenum and 3% tungsten, while C276 has approximately 16% chromium, 16% molybdenum and 4% tungsten.
These differences can influence corrosion performance. According to studies by our team at Nickel Alloy Plate Hub there is a particularly strong resistance of C22 to chloride-induced pitting, and crevice corrosion is noted, and its higher chromium content provides greater resistance to oxidising media than C276.
We also found that in the comparative testing done in saturated wet chlorine, C22 demonstrated less localised corrosion than C276 under the test conditions described.
Therefore, choosing between C22 and C276 should involve the actual chemicals, concentrations, temperatures, pressure, contamination, welding requirements and operating conditions.
What About Hastelloy C22 Plate Price Per Kg?
As per our recommendation, the Hastelloy C22 plate price per kg should never be evaluated independently of material quality and specification.
Nickel, chromium, molybdenum and tungsten are significant alloying constituents, while manufacturing route, plate dimensions, thickness, quantity, certification, testing, origin and market conditions can all affect the final quotation.
Consequently, when comparing a Hastelloy C22 plate price, you need to request a detailed ‘Get a Quote’ specifying the following:
- UNS designation — N06022
- Applicable ASTM specification
