Exploring the Remarkable World of Hastelloy C276 Foil

Hastelloy C276, a nickel-molybdenum-chromium alloy, is renowned for its exceptional resistance to a wide range of corrosive environments. One of the many forms in which this remarkable material is available is Hastelloy C276 foil. In this article, we will delve into the world of Hastelloy C276 foil, exploring its composition, properties, and the diverse applications that make it a vital material in industries where corrosion resistance is of utmost importance.

Composition of Hastelloy C276

Hastelloy C276 is a member of the Hastelloy family, which is known for its exceptional resistance to corrosion, particularly in harsh and aggressive environments. The composition of Hastelloy C276 consists of the following key elements:

  1. Nickel (Ni): Nickel is the primary component of Hastelloy C276, accounting for approximately 57% of its composition. Nickel is essential for enhancing the material’s corrosion resistance, ductility, and strength.
  2. Molybdenum (Mo): Molybdenum, constituting about 16-17% of Hastelloy C276, plays a critical role in providing resistance to localized corrosion, such as pitting and crevice corrosion. It also contributes to the alloy’s overall strength.
  3. Chromium (Cr): Chromium, at around 15-16%, adds to the alloy’s resistance to a wide range of corrosive substances. It helps in the formation of a passive oxide layer on the surface, preventing further corrosion.
  4. Tungsten (W): In small quantities, tungsten enhances the material’s resistance to high-temperature and high-velocity corrosive environments.
  5. Iron (Fe): Iron, though present in Hastelloy C276, is intentionally kept at low levels (less than 5%) to minimize the risk of sensitization, which can lead to intergranular corrosion.
  6. Other Elements: Hastelloy C276 may also contain trace amounts of different elements, such as carbon, sulfur, cobalt, and silicon, depending on the specific manufacturing process and requirements.
