Chemical composition

Hastelloy C276 is a high-performance corrosion-resistant alloy material produced by Haynes International as a nickel based alloy. It is composed of approximately 65% nickel (Ni), 15-17% molybdenum (Mo), 14.5-16.5% chromium (Cr), 3-4% iron (Fe), 2.5% cobalt (Co), 1% manganese (Mn), and a small amount of elements such as carbon (C), silicon (Si), phosphorus (P), and sulfur (S).

Product Features and Applications

The main characteristic of Hastelloy C276 is its extremely high corrosion resistance. It can resist a variety of organic and Mineral acid, oxides, reducing agents and other chemicals, especially in acidic environments. In addition, Hastelloy C276 also has excellent resistance to stress corrosion cracking, exhibiting excellent performance in high-temperature, high-pressure, and highly corrosive environments. Therefore, it is widely used in equipment and pipelines in fields such as chemical, petroleum, pharmaceutical, and food processing, as well as in the manufacturing of equipment such as heat exchangers, reactors, valves, pumps, and centrifuges.

Product performance

Hastelloy C276 has excellent corrosion resistance due to its unique chemical composition. Among them, the addition of molybdenum can improve the corrosion resistance of the material, chromium can increase the oxidation resistance of the material, and the addition of cobalt can improve the thermal stability of the material. In addition, the addition of chromium and molybdenum can also improve the strength and hardness of the material, while maintaining its excellent plasticity and toughness.

Hastelloy C276 not only has good corrosion resistance, but also has good processability and weldability. It can be processed and manufactured through various processing techniques, such as forging, rolling, casting, and cold working. In addition, Hastelloy C276 is also applicable to various common welding methods, including TIG welding, MIG welding and Arc welding. This makes Hastelloy C276 easy to connect and assemble with other materials during use, improving its flexibility and reliability in practical applications.

In summary, Hastelloy C276 is a high-performance corrosion-resistant alloy material with excellent corrosion resistance, stress corrosion cracking resistance, and thermal stability, widely used in equipment and pipelines in fields such as chemical, petroleum, pharmaceutical, and food processing. At the same time, Hastelloy C276 also has good machinability and weldability, which can be processed and manufactured through various processing processes, making it more widely applicable in practical applications.
