Haynes® 230

Haynes® 230 / UNS N06230

Haynes® 230 is a nickel-based superalloy that combines excellent high-temperature strength with exceptional resistance to oxidation, nitrogen, and hydrogen environments, and carburization. The alloy remains stable under prolonged exposure to high temperatures up to about 1150°C, without significant thermal embrittlement occurring.

These performances make Haynes® 230 extremely suitable for applications in the most extreme thermal and chemical conditions.

Properties of Haynes® 230

Haynes® 230 is a solution-strengthened alloy, meaning its mechanical strength comes from its composition and microstructure, without the need for precipitation hardening. The alloy offers excellent oxidation resistance up to 1150°C and withstands chemically aggressive atmospheres including nitrogen, hydrogen, and carbon-rich environments.

The stability of the microstructure prevents embrittlement during prolonged thermal exposure, which is crucial for the lifespan of components in continuously operating systems. Haynes® 230 is also highly weldable and formable, simplifying processing and manufacturing.

Thanks to this combination of properties, Haynes® 230 is often chosen for applications where other superalloys fall short.

Applications of Haynes® 230

Haynes® 230 is widely used in environments where extreme heat, chemical aggression, and structural reliability are required. Examples of applications include:

Gas turbine engines and combustion systems
Chemical and petrochemical plants
Power plants
Industrial heating installations and furnaces
Heat exchangers and heat shields

With its combination of high-temperature strength, oxidation resistance, and mechanical stability, Haynes® 230 is a top choice in thermally demanding sectors.

Haynes® 230 is the superalloy for maximum performance in extreme temperatures and chemically aggressive conditions.
