Alloy 214 (UNS N07214)

Alloy 214 / UNS N07214

Alloy 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, Alloy 214 has excellent resistance to carburization and delivers reliable performance in chloride-containing and high-temperature environments.

Properties of Alloy 214

Alloy 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 Alloy 214 an excellent choice for complex and demanding processes.

Applications of Alloy 214

Alloy 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, Alloy 214 is a reliable choice for high-quality thermal systems and process equipment.

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