Haynes® 214

Haynes® 214 / UNS N07214

Haynes® 214 is a nickel-based superalloy that offers exceptional oxidation resistance up to 1260°C. The alloy is specifically designed for use in the solution-annealed condition starting at 980°C, where it maintains reasonable strength, comparable to that of Inconel® Alloy 601.

In addition to oxidation resistance, Haynes® 214 has excellent resistance to carburization and delivers reliable performance in chloride-containing and high-temperature environments.

Properties of Haynes® 214

Haynes® 214 is distinguished by its superior oxidation resistance at extremely high temperatures, enabled by a protective aluminum-rich oxide film. Although the alloy can be strengthened through precipitation treatment below 925°C, it is primarily intended for use in the annealed condition at higher temperatures.

In this state, the material remains mechanically strong and structurally stable, and can be easily cold-formed. For hot forming, temperatures above 1040°C are required. The alloy is weldable, though precautions are needed during clamping to prevent stress cracking.

The resistance to carburization, oxidation, and aggressive gases like chlorine makes Haynes® 214 an excellent choice for complex and demanding processes.

Applications of Haynes® 214

Haynes® 214 is utilized in environments where extreme heat and chemical resistance are required. Typical applications include:

Industrial heating systems
Clean firing of electronic components
Clean firing of ceramic parts
High-temperature transport and furnace constructions
Applications in chemical and material processing

Due to its performance at extreme temperatures and in aggressive media, Haynes® 214 is a reliable choice for high-quality thermal systems and process equipment.

Haynes® 214 is the superalloy for applications requiring maximum oxidation resistance, structural integrity, and versatile workability.
