    Cr25Ni20 Nickel-Chromium-Iron Alloys High-Temperature Resistance


    Cr25Ni20 is a nickel-chromium-iron alloy composed of approximately 25% chromium, 20% nickel, and the remainder iron, designed for excellent performance in high-temperature and corrosive environments. This alloy offers a superior combination of oxidation resistance, thermal stability, and mechanical strength, making it well-suited for industrial applications.

    Known for its exceptional resistance to scaling and oxidation at elevated temperatures, Cr25Ni20 performs effectively in environments exposed to high heat and aggressive chemicals. It also provides good creep and stress rupture strength, ensuring reliability in prolonged high-stress conditions.

    The alloy is commonly used in applications such as heat exchangers, furnace components, and industrial heating systems. Its resistance to carburizing and oxidizing atmospheres makes it suitable for chemical processing, power generation, and metallurgical industries. Additionally, its weldability and formability allow for versatility in fabrication.

    In summary, Cr25Ni20 is a durable, high-performance material ideal for high-temperature and chemically aggressive environments, valued for its reliability and cost-effectiveness.
