What is Hastelloy material?

Hastelloy material, also known as Hastelloy alloy, is a metal material with special properties and wide application value. It is named after American engineer Harry Coebe. It is mainly composed of nickel, cobalt, chromium, molybdenum and other elements. It has high strength, high hardness, wear resistance, corrosion resistance and other properties. Hastelloy is the general name for the commercial grades of nickel-based corrosion-resistant alloys produced by Hastelloy International Company of the United States, including several different grades of alloys, such as Hastelloy B-2, Hastelloy C-4, etc.

Characteristics of Hastelloy Alloy


  • Corrosion resistance: Hastelloy material has excellent corrosion resistance to most corrosive media in both oxidizing and reducing atmospheres. It is particularly resistant to wet chlorine, various oxidizing chlorides, chloride salt solutions, sulfuric acid and oxidizing salts, and has good corrosion resistance in low and medium temperature hydrochloric acid. At the same time, Hastelloy also has high resistance to pitting corrosion, crevice corrosion and stress corrosion.
  • Thermal stability: Hastelloy material has good thermal stability and can maintain stable performance in high temperature environments. For example, Hastelloy C-4 has good thermal stability, toughness and corrosion resistance at 650-1040 degrees Celsius.
  • Mechanical properties: Hastelloy materials have high strength and hardness and can meet various mechanical performance requirements.

Classification of Hastelloy Alloy


Hastelloy is mainly divided into two categories: nickel-chromium alloy and nickel-chromium-molybdenum alloy. Different alloy grades have different chemical compositions and mechanical properties and are suitable for different application scenarios. For example, Hastelloy B-2 is a nickel-molybdenum alloy with excellent corrosion resistance in reducing environments; while Hastelloy C-276 has good resistance to oxidizing and moderately reducing corrosion and has excellent stress resistance corrosive ability.

Application Areas

Hastelloy materials have important applications in aerospace, shipbuilding, chemical industry, medical equipment and other fields. In the chemical and petrochemical fields, Hastelloy is widely used in transportation and storage equipment for various corrosive media due to its excellent corrosion resistance. Hastelloy is also favored for its good corrosion resistance in industrial fields such as flue gas desulfurization, pulp and papermaking, and environmental protection. In addition, in the field of medical devices, Hastelloy is also used to manufacture some parts that require corrosion resistance and high strength.

Market Position of Hastelloy Alloy


Hastelloy materials occupy an important position in the global metal materials market with their excellent performance and wide range of applications. With the development of the global economy and the acceleration of industrialization, the market demand for Hastelloy materials continues to grow. At the same time, with the continuous advancement of science and technology and the continuous emergence of new material technologies, Hastelloy materials are also constantly developing and innovating to meet the needs for high-performance metal materials in different fields.


To sum up, Hastelloy material is a metal material with special properties and wide application value. Its excellent performance, multiple classifications and wide range of applications make it an important position in the global metal materials market.
