Hastelloy C276 strip is made with the alloy of nickel, chromium, and molybdenum.
Due to excellent corrosion and high-temperature resistance, Hastelloy C276 strips are used in chemical process industry.
This grade strip is mostly used in the oil and gas field.
Hastelloy C276 strips are used to make high-temperature gas path components for the chemical industry’s pipes, valves, turbine combustors, flame holders, liners, and pressure vessels for some nuclear reactors and chemical reactors.
Hastelloy C276 strip has low silicon and carbon contents and is easily weldable; therefore, most chemical process industries use this material in chemical processes.
What is Hastelloy C276 strip?
It is believed that HASTELLOY C276, a wrought alloy of Nickel, chromium, and molybdenum, is the most versatile corrosion-resistant material of other alloys.
We can make the Hastelloy C276 strips by hot and cold rolling processes. We can quickly achieve the desired surface finish and thickness through these processes.
The Hastelloy C276 strips show exceptional resistance to stress-corrosion cracking, staining, and oxidizing environments up to 1037°C. Excellent resistance to a variety of chemical conditions can be obtained by alloy C276.

Why Hastelloy C276 strips are mostly used in the chemical industry?
The chemical processing sector has used Hastelloy C276 for almost fifty years.
There was an issue of weldability with previous alloys, which meant that there were extremely few ways for engineers to create machines without sacrificing performance.
Hastelloy C276 was developed as a result of the need to make a new alloy to satisfy the requirements of the affected industries and individuals.
Hastelloy C276 can resist chemicals like oxidizing salts and ferric and cupric chlorides; even when those solutions are effective, it is a fundamental factor for the use of Hastelloy C276 in the chemical processing industries.
The high amounts of Nickel and Molybdenum in C276 alloy, like other Hastelloy alloys, resulted in higher corrosion resistance and resistance to cracking and stress-corrosion breakdown.
Difference between Hastelloy C22 strips and Hastelloy C276 strips
Both Hastelloy C276 and C22 strips are made by their respective alloys with considerably higher chromium content than other Hastelloy materials.
They are primarily composed of Nickel, chromium, and molybdenum.
As a result, while both of these materials are alloys made up of several metals, the main difference between Hastelloy C22 and C276 strips is the different compositions of the individual metals.
Because of this difference, Hastelloy C22 and C276 strips have various uses in the chemical sector.
Properties of Hastelloy C276 strips
Hastelloy C276 strips can resist most oxidizing conditions and shows excellent corrosion resistance in reducing environments.
Compared to others metals strips, alloy C276 can survive in high hydrogen sulfide situations.
The final shape of alloy C276 is forged because it is a wrought alloy. The alloy is workable using traditional cold-working and hot-working techniques.
Even the toughest, most resilient alloys may start to fail at specific temperatures. Alloy C276 can function in oxidizing conditions up to 1,900°F without pitting, corrosion, or cracking.
In high-temperature conditions, the Hastelloy C276 strips can easily do its functions. Alloy C276 strip has excellent general workability due to the presence of molybdenum, and also this alloy can be machined easily in the annealed condition.
How to produce Hastelloy C276 strips in the chemical process industry?
In the production of Hastelloy C276 uses Nickel to increase the corrosion resistance. Molybdenum and chromium are additionally used in this process. Hastelloy comes in a variety of grades, each of which is chemically optimized for a particular set of qualities.
Hastelloy performs well in highly corrosive conditions due to its characteristic high molybdenum and chromium content. The addition of molybdenum also improves general workability. These alloys are more ductile and easily fabricated. Hastelloy alloys are very demanded in chemical process industries.
Hastelloy is a metal alloy created by mixing raw materials while they are still liquid at high temperatures. There are different classes, each with a unique chemical makeup. A mixture may have Nickel as the remaining component and up to 25% chromium, 5% to 30% molybdenum, and 0% to 30% iron. Further additions may include titanium, carbon, tungsten, and vanadium, depending on the grade.
The Hastelloy C276 strips are made of C276 alloy through hot and cold working processes. For cold working, alloy C276 strip must be in the annealed state if a high degree of cold working is required; then in the process, annealing is very important.
Why are Hastelloy C276 strips the best corrosion-resistant?
An important design factor when selecting the material can be corrosion resistant.
Corrosive conditions may be present during some fluid operations, which can cause stress corrosion cracking in components. Materials that can resist this type of mechanical breakdown can be required in corrosive environments.
Where excellent corrosion resistance is required, Nickel-based alloys are a good material choice. Nickel can increase strength and hardness while maintaining ductility.Alloys based on Nickel may be able to prevent stress corrosion cracking in heat exchangers.
For applications requiring corrosion resistance, a variety of nickel-based alloys are available.
One of the most widely used corrosion-resistant metals for the fluid processing sector is Hastelloy C276. The elements that make up the alloy are Nickel, molybdenum, chromium, and a small quantity of tungsten. Usually, the alloy has more than 50% nickel.
Conclusion
It is true the Hastelloy C276 is a very useful alloy due to its wide range of applications.
The Hastelloy C276 strips are primarily used in the chemical process industry due to their strength, surface finish, and excellent resistance against corrosion.
