Incoloy 800 Bar: High-Temperature Strength for Petrochemical and Furnace Applications
At our company, we specialize in producing Incoloy 800 Bar, a high-performance alloy designed specifically for demanding environments where high-temperature strength is crucial. Our Incoloy 800 Bar stands out in petrochemical and furnace applications, offering exceptional resistance to oxidation, carburization, and corrosion while maintaining structural integrity at elevated temperatures. If you're searching for reliable Incoloy 800 round bar suppliers, you've come to the right place—we craft these bars with precision to meet the toughest industry standards.
Let's dive into what makes our Incoloy 800 Bar so special. This nickel-iron-chromium alloy, often referred to as UNS N08800, combines about 30-35% nickel, 19-23% chromium, and a balance of iron with small additions of aluminum and titanium. These elements work together to create a material that's tough against heat and harsh chemicals. Our Incoloy 800 Bar isn't just another metal rod; it's engineered for longevity in places where ordinary steels would fail quickly. We produce it in various forms like round bars, hex bars, and custom shapes, ensuring it fits seamlessly into your projects.

One of the standout features of our Incoloy 800 Bar is its high-temperature strength. It can handle service temperatures up to 1500°F without losing its mechanical properties significantly. For instance, in annealed condition, it boasts a tensile strength of around 80 ksi and a yield strength of about 25 ksi at room temperature, and it retains much of that strength even as things heat up. This makes our Incoloy 800 Bar perfect for furnace components like radiant tubes, muffles, and retorts. In petrochemical settings, it's ideal for cracker tubes, pigtails, and heat exchangers where exposure to aggressive gases and high heat is constant. We ensure every batch of our Incoloy 800 Bar undergoes rigorous testing for creep and rupture strength, so you get consistent performance every time.
