Hastelloy C276 is a nickel-molybdenum-chromium superalloy that Haynes International developed. It is designed to offer excellent resistance to corrosion in the most challenging environments. It is particularly well-suited for use in harsh chemical processing environments when used in its plate form. This blog post will explore the properties, uses, and composition of Hastelloy C276 plates.
What Are Hastelloy C276 Plates?
Hastelloy C276 Plates are high-performance alloy plates manufactured using a nickel-molybdenum-chromium alloy. These plates have superior corrosion resistance in a wide range of chemical environments. Their unique combination of good mechanical strength and excellent corrosion resistance make them ideal for many applications, including chemical processing, pollution control, pulp & and paper production, power generation, and more. They are also heat resistant to higher temperatures than other similar alloys.
Composition Of Hastelloy C276
This superalloy contains nickel, cobalt, molybdenum, chromium, iron, and tungsten. Its high nickel content resists chloride-induced pitting, crevice corrosion, and stress corrosion cracking. The presence of molybdenum and chromium enhances its resistance to oxidizing and reducing environments. Including tungsten and cobalt also contributes to its corrosion resistance and high-temperature strength.
Properties Of Hastelloy C276 Plates
Hastelloy C276 plates possess excellent corrosion resistance to various chemicals, including sulfuric acid, hydrochloric acid, chlorine, solvents, and oxidizers. They also offer exceptional resistance to stress corrosion cracking and pitting. Additionally, these plates can withstand high temperatures and pressure, making them suitable for use in harsh chemical processing environments.
Uses Of Hastelloy C276 Plates
Given its superior corrosion resistance and durability, Hastelloy C276 plates are widely used in various industries, including chemical processing, petroleum refining, and power generation. These plates are also used in heat exchangers, reactors, and distillation columns. They are an excellent choice for applications where high temperatures and pressure are a concern and where corrosion resistance is essential.
Manufacturing Of Hastelloy C276 Plates
Hastelloy C276 plates are manufactured using a range of methods, including hot rolling, cold rolling, and annealing. The hot rolling process involves heating the alloy to a high temperature and then rolling it into the desired thickness. Cold rolling is used to improve the mechanical properties of the plates. Annealing is used to reduce the risk of cracking during the processing of the plates.
Conclusion
In conclusion, Hastelloy C276 plates are an excellent choice for use in harsh chemical processing environments. They offer superior corrosion resistance, and durability, and can withstand high temperatures and pressure.
