Alloy 602CA UNS N06025 Heat-Resisting Superalloy Bars and plates
Nickel-chromium-tungsten-molybdenum alloy boasts exceptional oxidation resistance, high-temperature strength, and long-term thermal stability. Thanks to its unique solid-solution strengthening and carbide-reinforcement mechanisms, it maintains outstanding creep resistance and structural integrity even in environments as high as 1200℃.
Applications of Alloy 602CA
In the aerospace industry, it is the material of choice for hot-end components such as turbine engine combustion chambers, transition sections, and afterburners. In the energy sector, it is widely used in heavy-duty gas turbine burners, flame tubes, and heat-exchange piping systems. In the heat treatment industry, it is employed in high-temperature furnace rollers, radiation tubes, and sintering fixtures—among other heat-resistant equipment.
