What is Hastelloy®?

Hastelloy® is a registered trademark of Haynes International, covering a group of nickel-based superalloys. These alloys are known for their outstanding corrosion resistance and their ability to maintain strength at high temperatures. Hastelloy alloys are primarily composed of nickel, with added molybdenum and chromium to enhance their corrosion and heat resistance.

Properties of Hastelloy Alloys

Hastelloy alloys offer several advantages for the engineering industry. They exhibit excellent resistance to both oxidizing and reducing environments, making them suitable for a wide range of chemical processes. Additionally, they are easy to form and weld, which simplifies their use in various applications.

Types of Hastelloy Alloys

There are several types of Hastelloy alloys, each designed for specific purposes:

  • Hastelloy B-3: This alloy contains a high concentration of molybdenum and nickel, giving it excellent durability in reducing environments such as hydrochloric acid.
  • Hastelloy C-276: Known as a versatile and corrosion-resistant alloy, it withstands both oxidizing and reducing chemicals. It is widely used in the chemical industry.
  • Hastelloy X: This alloy combines high strength, oxidation resistance, and good formability, making it suitable for use at high temperatures, such as in the aerospace industry.

Use of Hastelloy Alloys in the Engineering Industry

In the engineering industry, Hastelloy alloys are widely used because of their excellent corrosion resistance and heat tolerance. They are particularly well suited for components exposed to harsh chemical environments and high temperatures, such as reactors, piping, and valves. Their good formability and weldability also make them ideal for complex structures and devices.

Summary

Hastelloy® alloys are nickel-based superalloys that offer outstanding corrosion resistance and heat tolerance. Their versatility and formability make them valuable materials in the engineering industry, especially for applications that require high performance in challenging conditions.
