Hastelloy alloys are widely popular in the manufacturing industry for their robustness, durability, and superior performance in harsh environments. Hastelloy X and Hastelloy Round Bars are two popular alloy variations known for their exceptional strength and resistance to high temperatures and corrosion. When it comes to selecting the appropriate option for your project, choosing between Hastelloy X round bars and Hastelloy round bars can be a tough call. So, in this blog post, we’ll conduct a showdown between the two and determine which option reigns supreme.
What is Hastelloy X Round Bar and Hastelloy Round Bar?
Hastelloy X Round Bars are high-temperature, corrosion-resistant alloys providing superior performance in harsh environments. These round bars possess excellent creep rupture strength at temperatures ranging from 1500 to 2000 degrees Fahrenheit and have higher resistance to oxidation than the traditional Hastelloy round bars. Additionally, Hastelloy X boasts significantly increased crevice corrosion and stress cracking resistance when compared to other alloy materials. The combination of exceptional properties makes this material ideal for extreme conditions requiring extended service life!
Hastelloy Round Bars
Hastelloy round bars are made of a nickel-chromium-molybdenum alloy that has been specially designed for use in high-temperature applications. The bars have excellent resistance to oxidation and carburization, and they can be used in both vacuum and atmosphere furnaces.

Difference Between Hastelloy X Round Bar vs Hastelloy Round Bar
Chemical Composition
Hastelloy X, also known as Hast X, is made with a mix of nickel, cobalt, iron, and chromium, whereas Hastelloy boasts a combination of nickel, molybdenum, and chromium. The higher molybdenum content in Hastelloy provides it with better resistance against localized corrosion by reducing the chance of pitting and crevice corrosion. However, if you’re looking for a material that can withstand high-temperature applications, Hastelloy X is the better choice, as it contains more cobalt and iron, making it more oxidation-resistant.
Applications
Both Hastelloy X round bars and Hastelloy round bars are used in many applications, but the former is specifically designed to operate in high-temperature situations. For example, if you require a material that can withstand temperatures as high as 1200°C, Hastelloy X is ideal. On the other hand, Hastelloy round bars have been engineered with exceptional corrosion resistance and can offer better performance in chemicals and acidic environments.
Hastelloy X round bars are typically used in furnace applications where temperatures exceed 2200°F (1200°C), such as in heat-treating baskets and trays, radiant tubes, retorts, and muffles. Hastelloy round bars are also often used in petrochemical processing equipment, such as catalyst supports, packing rings, and valve seats.
Fabrication
Hastelloy X round bars are generally more challenging to fabricate than Hastelloy round bars due to their hardness. Hastelloy X is known to be exceptionally difficult to machine because of its higher cobalt and iron content, resulting in increased tool wear. Hastelloy round bars, conversely, can be more effortlessly machined, rolled, or welded since they’re softer.
Cost
The cost is another crucial factor to consider when choosing between Hastelloy X round bars and Hastelloy round bars. Due to its higher content of iron and cobalt, Hastelloy X is more expensive than Hastelloy round bars. However, if your application necessitates the use of materials that provide better thermal stability and longer operational lifetimes and you can afford a little splurge, then Hastelloy X round bars are the suitable option.
Hastelloy X round bars are much more cost-effective than regular Hastelloy round bars. This is because Hastelloy X contains a higher percentage of chromium and manganese, which provides additional strength and hardness at a lower alloy cost. Because of this, the production costs associated with producing Hastelloy X are significantly lower compared to standard Hastelloy alloys, resulting in a cheaper end-product for the consumer.
Conclusion:
In summary, both Hastelloy X round bars and Hastelloy round bars are versatile and effective options. When it comes to selecting between Hastelloy X and Hastelloy round bars, it’s important to consider your project’s specific requirements. If your project necessitates excellent corrosion resistance, then Hastelloy round bars are the way to go. For high-temperature applications, Hastelloy X round bars would be the better option. Consider your budget as well, as Hastelloy X round bars are more expensive than Hastelloy round bars. Ultimately, both alloys are high-performance materials and have their individual strengths and weaknesses.
