Regarding corrosion-resistant alloys, Hastelloy C-22 offers some of the highest performance properties on the market. This nickel-based alloy is highly corrosion-resistant and can withstand harsh conditions, making it a popular option in industries requiring exceptionally durable materials. This blog post will explore why Hastelloy C-22 sheets, plates, and coils are superior to other nickel alloy grades.

What are Hastelloy C-22 Sheets, Plates, and Coils?

Hastelloy C-22 Sheets, Plates and Coils are a nickel-chromium-molybdenum alloy designed for superior corrosion resistance in various environments. It has excellent general corrosion resistance to oxidizing and reducing media and outstanding localized corrosion resistance, including intergranular attack and stress corrosion cracking. It is especially resistant to pitting and crevice corrosion in chloride-bearing media such as seawater, brines, hypochlorite solutions, sulfuric acid compounds, and other reducing agents commonly encountered in chemical process applications.

Superior Corrosion Resistance

Hastelloy C-22 is known for its superior corrosion resistance properties, especially in oxidizing chloride environments. It is highly effective in resisting crevice corrosion, pitting, and stress corrosion cracking, making it a top choice in industries such as chemical processing, pollution control, and oil and gas. Additionally, Hastelloy C-22 has a long service life, reducing the need for frequent maintenance or replacement.

Wide Range of Applications

Hastelloy C-22 is versatile in its range of potential applications. It is suitable for chemical plants’ heat exchangers, piping systems, pressure vessels, and other components. Its strength and durability are enhanced at elevated temperatures, allowing it to perform reliably even in harsh environments. The alloy’s unique composition also gives it high resistance to hydrochloric and sulfuric acids, making it well-suited for acid production facilities.

Excellent Weldability

One of Hastelloy C-22’s standout properties is its excellent weldability. The alloy can be easily welded using common techniques such as TIG, MIG, and SMAW, making it a preferred material in industries that rely on welding for component assembly. The ability to weld Hastelloy C-22 without causing significant loss of corrosion resistance is a major advantage over other nickel alloys that can experience corrosion issues in the heat-affected zones.

High Performance in Highly Corrosive Environments

Hastelloy C-22 is particularly effective in highly corrosive environments, offering superior performance to other nickel alloys such as Hastelloy C-276. In situations where higher levels of oxidation and corrosion resistance are required, C-22 is a better option. It has been tested and proven to withstand harsh chemicals, including hydrochloric and sulfuric acid, and can perform even in environments with high levels of chlorides or oxidizing chemicals.

Long Service Life

Because of its superior corrosion resistance, Hastelloy C-22 has a longer service life than other nickel alloys. This means that industries that use this material can reduce costs associated with frequent maintenance or replacements. Components made from Hastelloy C-22 can operate for years without showing any signs of corrosion, making it a reliable and cost-effective option for businesses.


In summary, Hastelloy C-22 sheets, plates, and coils offer superior properties over other nickel alloys. From its exceptional corrosion resistance to its versatility in various industrial applications, Hastelloy C-22 stands out as a top-performing material. Its ability to withstand harsh chemicals and environments while maintaining its integrity and strength and its excellent weldability make it a sought-after material in many industries. If you’re looking for a high-performance material with a long service life, consider using Hastelloy C-22 for your next project.
