Alloy 230 (UNS N06230)

Alloy 230 / UNS N06230

Alloy 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 Alloy 230 extremely suitable for applications in the most extreme thermal and chemical conditions.

Properties of Alloy 230

Alloy 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. Alloy 230 is also highly weldable and formable, simplifying processing and manufacturing.

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

Applications of Alloy 230

Alloy 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, Alloy 230 is a top choice in thermally demanding sectors.

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