    Cr20Ni35 The Top Nickel-Chromium-Iron Alloy for Extreme Conditions and Harsh Chemical Environments

    Cr20Ni35 The Top Nickel-Chromium-Iron Alloy for Extreme Conditions and Harsh Chemical Environments


    Cr20Ni35 is a high-performance austenitic steel alloy composed of 20% chromium and 35% nickel, designed for applications that demand superior resistance to high temperatures, oxidation, and corrosion. The alloy's high chromium content provides exceptional oxidation resistance, while the high nickel content enhances its toughness, ductility, and resistance to stress-corrosion cracking. These properties make Cr20Ni35 ideal for high-temperature environments such as furnaces, heat exchangers, and chemical reactors.


    With an austenitic structure, Cr20Ni35 remains non-magnetic and exhibits excellent weldability and formability, allowing it to be used in a variety of complex, welded applications. The alloy also maintains its mechanical strength and corrosion resistance in both acidic and alkaline conditions, making it suitable for use in harsh chemical environments. Additionally, it is resistant to thermal cycling and maintains good performance even under dynamic or cyclic loads.


    Cr20Ni35's combination of high-temperature resistance, corrosion resistance, and good mechanical properties makes it widely used in industries such as power generation, aerospace, and chemical processing, particularly in components exposed to extreme conditions. Its ability to withstand both high temperatures and corrosive environments makes it an ideal material for long-term, high-performance applications.
