Inconel 800

Hello, this is Dong-A Special Metals Co., Ltd. As previously introduced, Inconel alloys are widely used across high-demand industries. Today, we focus on Inconel 800, a representative nickel-iron-chromium-based superalloy designed for long-term use in high-temperature environments.

This highly functional material plays a critical role in the steelmaking and alloying industries, especially in line with the current push for ESG (Environmental, Social, and Governance) management. At Dong-A Special Metals, we process industrial scrap into raw materials through precise sizing and sorting, supporting a sustainable resource circulation system.


What Is Inconel 800?

Inconel 800 is a high-performance alloy composed mainly of nickel (30–35%), chromium (19–23%), and iron. This composition grants it exceptional resistance to oxidation, carbonization, and nitriding at elevated temperatures. Its melting point ranges between 1357–1385°C, and its density is approximately 7.94 g/cm³.

The alloy retains tensile strength over 500 MPa even at high temperatures and shows excellent resistance to creep deformation, thermal shock, and repeated thermal cycling. These features make Inconel 800 ideal for use in:

- Heat exchangers

- Boiler tubes in power plants

- Petrochemical processing equipment

- Nuclear reactors and SMRs (Small Modular Reactors)


Key Benefits of Inconel 800

1. Superior Heat and Oxidation Resistance

The high chromium content forms a protective oxide layer, preventing corrosion even under continuous high-temperature exposure. This makes the alloy suitable for long-term industrial use.


2. Excellent Structural Stability

Even after prolonged exposure to high temperatures, Inconel 800 maintains a stable metallographic structure, avoiding grain growth or material softening. This ensures long-term operational safety and reliability.


3. Resistance to Carbon and Nitrogen Atmospheres

Its high resistance to carburizing and nitriding atmospheres makes it invaluable in petrochemical plants and high-carbon pyrolysis environments.


4. Corrosion Resistance in Harsh Conditions

Inconel 800 resists corrosion in environments containing chlorides, sulfides, and other aggressive elements, making it ideal for chemical processing and thermal energy systems.


Why Inconel 800 Matters for the Future

In the era of carbon neutrality and clean energy, the Inconel 800 series is gaining attention as a strategic material. It supports the development of:

- Hydrogen fuel power systems

- Supercritical and ultra-supercritical power plants

- Next-generation nuclear technologies (SMRs)

At Dong-A Special Metals, we actively recycle high-performance alloys like Inconel 800, contributing to Korea's material self-sufficiency. Our goal is to strengthen the domestic rare metal recycling industry and create a sustainable circular economy.


Partner with Us for a Sustainable Future

We invite steelmakers, materials engineers, and alloy consumers to explore the advantages of using recycled Inconel 800 in their applications. Please contact us for further discussions—we're committed to supporting innovation, localization, and sustainability in the Korean alloy market.
