Hastelloy Foil

Hastelloy foil is a thin and flexible sheet of Hastelloy which is a group of nickel based alloy that exhibits high resistance to corrosion, high temperature strength and good mechanical strength. These foils are generally available in several grades such as Hastelloy C 276, C 22 and B 2 which have been developed to operate in dissimilar corrosive and thermal conditions. Hastelloy foil is used in chemical processing, aerospace, marine and pollution control industries where the material has to withstand severe conditions such as attack by acids, chlorides and high temperatures. Due to its thin structure, it is suitable for applications where accurate and light weight material solutions are needed without sacrificing performance.

Advantages of Hastelloy Foil

These flexible Hastelloy Foil offer numerous benefits for industrial applications.  

•  Outstanding Corrosion Resistance: Hastelloy foil is chemically immune to a broad range of corrosive media such as strong acids, alkalis and oxidizing agents.
•  High-Temperature Stability: It has a very good strength and dimensional stability at high temperatures and therefore it is ideal for use at high temperatures.
•  Resistance to Stress Corrosion Cracking: Hastelloy foil is immune to stress corrosion cracking and is therefore suitable for use in highly corrosive chemical applications.
•  Pitting and Crevice Corrosion Resistance: The foil is intended to resist localized types of corrosion, for example pitting and crevice corrosion that are typical for severe conditions.
•  Lightweight yet Durable: Nonetheless, Hastelloy foil is very thin and light but it has high mechanical strength and durability in the long run.
•  Versatile Alloy Grades: It comes in different grades such as C276 and C22 which is designed for various operations to meet the required standards in various industries.
•  Oxidation Resistance: Hastelloy foil is capable of resisting oxidation in high-temperature conditions; thus, the material's surface will not corrode with time.
•  Precision Engineering: The foil is very thin and flexible, making it possible to use it in areas that would otherwise require thick material.

Hastelloy Foil offer several advantages that make them suitable for industrial and commercial applications.

Common Applications of Hastelloy Foil
