In the realm of corrosion-resistant alloys, Hastelloy C2000 vs C276 occupy a prominent place, each with unique characteristics that make them suitable for specific industrial applications. Both alloys are nickel-based superalloys that exhibit excellent resistance to a wide range of corrosive environments. However, there are several key differences between Hastelloy C2000 and C276 in terms of composition, mechanical properties, corrosion resistance, and applications.
Hastelloy C2000 vs C276: What’s the Difference?
Hastelloy C2000 vs C276 – 1. Composition
The composition of Hastelloy C2000 and C276 is what sets them apart. Hastelloy C2000 is an alloy with a high molybdenum content, which gives it its resistance to pitting and crevice corrosion in chloride-containing environments. It also contains chromium, iron, and tungsten, which contribute to its overall corrosion resistance.
On the other hand, Hastelloy C276 has a higher chromium content than C2000, along with molybdenum, nickel, and iron. The addition of tungsten and cobalt further enhances its corrosion resistance, particularly in aggressive media such as sulfuric acid.
Hastelloy C2000 vs C276 – 2. Mechanical Properties
Mechanically, Hastelloy C2000 and C276 exhibit different characteristics. Hastelloy C2000 offers good strength and ductility, making it suitable for applications that require both corrosion resistance and mechanical integrity. It also has good weldability and can be easily fabricated into complex shapes.
Hastelloy C276, on the other hand, is stronger and more ductile than C2000, making it a better choice for applications that require high strength and corrosion resistance. It also has superior fatigue resistance, making it suitable for dynamic loading conditions.
Hastelloy C2000 vs C276 – 3. Corrosion Resistance
Both Hastelloy C2000 and C276 exhibit excellent corrosion resistance, but their resistance profiles differ slightly. Hastelloy C2000 is particularly resistant to chloride-induced stress-corrosion cracking and pitting corrosion in seawater and other chloride-containing environments. It is also resistant to corrosion by reducing acids, such as sulfuric acid.
Hastelloy C276, on the other hand, offers even better resistance to a wide range of corrosive media, including oxidizing acids, reducing acids, and chloride-containing environments. Its high chromium content makes it resistant to corrosion by oxidizing agents, while its molybdenum and tungsten content enhance its resistance to reducing acids.
Hastelloy C2000 vs C276 – 4. Applications
The unique properties of Hastelloy C2000 and C276 make them suitable for different industrial applications. Hastelloy C2000 is commonly used in chemical processing equipment, pollution control systems, and off-shore oil and gas production equipment due to its resistance to chloride-induced corrosion.
Hastelloy C276, with its superior corrosion resistance, is widely used in more aggressive environments such as acid processing equipment, waste treatment systems, and high-temperature chemical processing applications. It is also used in the aerospace and nuclear industries due to its resistance to radiation-induced degradation.
