When it comes to building reliable and long-lasting heat exchangers in power plants, material choice is found to be very critical and a much more essential factor. At Mehta Metals, we understand the demanding environments of power or energy generation systems. That’s why Hastelloy C22 and Hastelloy C276 have transformed into the preferred alloys for heat exchangers across many industries.
Both alloys are known for their unique corrosion resistance, high-defining properties, and high-performance in extremely challenging temperatures. In this blog, we’ll explore why Hastelloy C22 for heat exchangers and Hastelloy C276 for heat exchangers are trusted worldwide.
What Is Hastelloy? & their Grades C22 & C276?
Hastelloy is a trademark name for corrosion-resistant metal alloys primarily composed of nickel, with varying amounts of molybdenum, iron, chromium, and cobalt.
The most commonly used grades in the potential and chemical industry are:
- Hastelloy C22 (UNS N06022)
- Hastelloy C276 (UNS N10276)
These alloys are significantly powerful in harsh chemical environments and are largely used in heat exchangers, reactors, pressure vessels, and condensers.
Why Choose Hastelloy C22 ASTM B575 for Heat Exchangers?
Fantastic Corrosion Resistance
Hastelloy C22 UNS N06022 plate for heat exchangers is too resistant to oxidizing and reducing compounds or agents. This makes it ideal for power plants where corrosive chemicals and high pressures are present heavily.
Relevant for Harsh Environments
Power plants are often surrounded by the environments of steam, acids, chlorides, and different corrosive substances. C22 Hastelloy plates can deal with these without pitting, crevice corrosion, or stress corrosion cracking.
Long-Term Cost Skill
Although the Hastelloy C22 plate price in India may be higher than conventional alloys, according to the prices we provide is competitive as compared to others and also provides assurance of a longer service life and lower maintenance needs, establishing it as a cost-effective solution in the long run.

Why Choose Hastelloy C276 ASTM B575 for Heat Exchangers?
Versatile and Durable
Hastelloy C276 UNS N10276 plate for power plants is the new industry favourite. Known for its toughness and durability, this alloy works well in both oxidizing and non-oxidizing environments.
Resistance to Severe Corrosive Controls
Power plants often require a range of temperature and pressure revisions. Hastelloy C276 plates are exceptionally resistant to:
- Hydrochloric acid
- Sulfuric acid
- Chloride-induced corrosion
- Seawater
Ideal for Energy Generation Equipment
Hastelloy C276 for heat exchangers helps reduce equipment failure and downtime. It can withstand any of the high thermal stress or pressure, making it ideal for boiler feedwater heaters, steam condensers, and new main components.
Applications in Power Plants of Hastelloy C22/Hastelloy C276 ASTM B575
Both Hastelloy C22 and C276 are used in:
Heat Exchangers
The high thermal conductivity and corrosion resistance make them accurate for shell and tube heat exchangers, plate heat exchangers, and fin-type exchangers.
Boilers & Condensers
Their ability to withstand ultimate heat and corrosive condensate makes them a reliable choice for steam and gas boiler systems.
Pollution Control Equipment
In the sectors of pollution control, Hastelloy alloys are generally employed in flue gas scrubbers and also in treating water in the wastewater treatment systems. This happens due to their ability to resist acrid & alkaline media.
Hastelloy C22 (UNS N06022) vs. C276 (UNS N10276): What’s the Difference?
| Property | Hastelloy C22 | Hastelloy C276 |
| UNS Number | N06022 | N10276 |
| Composition | More chromium (better oxidizing resistance) | More molybdenum (better reducing resistance) |
| Corrosion Resistance | Superior in oxidizing environments | Excellent in reducing environments |
| Weldability | Good | Good |
| Applications | Chemical reactors, heat exchangers | Heat exchangers, condensers, pollution control |
