What Are Heat-Resistant Alloys?
Heat-resistant alloys are a special group of materials designed for high-temperature environments. These alloys contain a minimum of 12% chromium to form a protective chromium oxide layer at high temperatures. Additional elements such as carbon, nitrogen, nickel, silicon, and aluminum enhance their properties. Rare earth metals are also incorporated to improve oxide adherence.
Some common heat-resistant alloys include,
Factors to Consider When Selecting Heat-Resistant Alloys
- Oxidation Resistance: Heat-resistant alloys with at least 12% chromium can form an oxide layer that protects them at high temperatures. Beyond the oxidation threshold, they become porous and brittle.
- Creep Strength: Creep is time-dependent deformation at elevated temperatures and constant stress. High creep strength alloys retain their shape, making them ideal for high-temperature applications.
- Carburizing and Nitriding: These processes introduce carbon and nitrogen into the material’s surface, enhancing wear resistance. Alloys with high nickel content are better suited for these environments.
- Vacuum Processing: The process environment should be void of oxygen. Therefore, high temperature oxidation does not tend to be a concern.
Common Applications of Heat-Resistant Alloys
- Thermal Processing: Used for bar baskets, serpentine grids, radiant tubes, and retorts.
- Chemical Processing: Used for flair tips, piping, steam methane reformers, and heat exchangers.
- Galvanizing Lines: Used for their corrosion resistance.
Heat-resistant alloys are also used in a wide range of industries including:
- Power Generation
- Aerospace
- Oil and Gas
- Steel Manufacturing
Conclusion
Heat-resistant alloys are at the heart of numerous high-temperature applications. Understanding their properties and how they behave in various environments is crucial to making the right material selection.

AL-6XN® Case Study
Coal-fired power plants generate flue gas as a byproduct of combustion. In many modern plants, especially those burning coal with high sulfur and chloride content, this flue gas can become highly corrosive to carbon steel and even conventional stainless steels.
RA 253 MA® vs 309/310
The main difference between RA 253 MA and both 309 and 310 stainless steel lies in alloy composition and resulting high‑temperature performance. RA 253 MA contains micro‑alloy additions of cerium, silicon, and nitrogen, which enhance oxidation resistance and creep strength at elevated temperatures. In addition, RA 253 MA has a lower overall nickel and chromium content, making it less susceptible to fluctuations in commodity pricing when compared to 309 and 310 stainless steels.
