High-Temperature Incoloy 800 Wire for Heat Treatment and Furnace Heating Elements

In high-temperature industrial environments, material reliability is everything. Processes such as heat treatment, petrochemical refining, and industrial furnace operations expose materials to extreme heat, oxidation, and carburization. In these conditions, conventional metals degrade quickly, leading to costly downtime and equipment replacement. Incoloy 800 wire was developed precisely to address these challenges, offering a balance of strength, stability, and resistance to high-temperature corrosion.

Our company specializes in the production and supply of high-performance alloys, and Incoloy 800 wire is a core part of our product portfolio. By supplying this wire to clients worldwide, we help ensure safe, efficient, and long-lasting performance in heat-intensive industrial systems.

Incoloy 800 wire is a nickel-iron-chromium alloy engineered for superior performance in elevated temperatures. Its chemical composition typically includes 30–35% nickel, 19–23% chromium, and the balance iron, with small additions of carbon, aluminum, and titanium. This blend provides the ideal balance of mechanical strength and resistance to oxidation and carburization at elevated service temperatures.

What makes Incoloy 800 unique is its ability to remain stable when exposed to long-term high temperatures up to 1100°C (2010°F). Unlike many stainless steels, which can suffer from loss of ductility or structural integrity, Incoloy 800 retains its mechanical properties, ensuring that equipment continues to perform safely and reliably.

The wire form of Incoloy 800 opens the door to a wide variety of high-temperature applications. Some of the most common include:

• Furnace heating elements: Incoloy 800 wire is wound into coils or grids that serve as heating elements in electric furnaces, kilns, and industrial ovens. Its resistance to scaling and carburization ensures long service life even in continuous operation.

• Heat treatment systems: In processes such as annealing, carburizing, and hardening, Incoloy 800 wire is used in fixtures, trays, and support grids. It maintains stability during repeated heating and cooling cycles.

• Petrochemical processing: In refinery heaters, reformers, and cracking units, Incoloy 800 wire withstands corrosive atmospheres containing sulfur and carbon compounds.

• Power generation: Boilers, superheaters, and heat exchangers in thermal power plants rely on materials like Incoloy 800 to perform under high heat and corrosive gases.

• Industrial equipment reinforcement: Its strength and corrosion resistance make it suitable for use in mesh screens, binding wires, and other components exposed to heat and chemical attack.

Performance in High-Temperature Environments

One of the standout properties of Incoloy 800 wire is its resistance to carburization, oxidation, and scaling. In high-temperature furnaces where carbon-rich gases can cause embrittlement, Incoloy 800 wire provides a reliable defense. Similarly, in oxidizing atmospheres, the protective chromium oxide layer forms a shield against scale buildup.

This long-term stability reduces equipment maintenance frequency, lowers replacement costs, and ensures consistent production in industries where downtime is highly expensive.

The global demand for Incoloy 800 wire is closely tied to trends in energy, materials processing, and environmental compliance. Several key drivers are influencing adoption:

• Expanding heat treatment industry: As more industries—automotive, aerospace, and toolmaking—require advanced heat-treated components, demand for reliable heating elements and fixtures is growing.

• Petrochemical growth: Chemical processing plants worldwide are increasing production capacity, requiring materials that can handle high-temperature and corrosive environments.

• Focus on efficiency and sustainability: Industries are under pressure to reduce energy waste and extend equipment lifespan. Incoloy 800 wire helps achieve these goals by providing reliable, long-term performance.

• Shift toward high-performance alloys: As stainless steels reach their limits in aggressive environments, companies are increasingly adopting nickel-based alloys like Incoloy 800 for critical applications.

While Incoloy 800 wire is highly effective, other alloys such as Incoloy 800H, Incoloy 800HT , and Inconel 600 offer slightly different balances of properties. Incoloy 800H wire includes higher carbon content and additional titanium and aluminum, improving creep resistance. Incoloy 800HT takes this further, providing superior performance in extremely high-temperature applications. Inconel 600, another nickel-based alloy, offers excellent resistance but at a higher cost for certain applications.

In this spectrum, Incoloy 800 wire provides a cost-effective and reliable option for heat treatment and furnace heating, where both oxidation resistance and strength are critical.
