Nickel-Chromium-Iron Alloy
Inconel 601
Inconel 601 is a nickel-chromium-iron solid solution strengthened alloy, widely used in engineering applications requiring heat and corrosion resistance. Its outstanding feature is exceptional high-temperature oxidation resistance, making it ideal for demanding thermal environments. The alloy also provides good resistance to aqueous corrosion, high mechanical strength, and excellent formability, machinability, and weldability. It maintains good thermal strength and plasticity below 700°C and can be strengthened through cold working. Additionally, it is suitable for welding and brazing, performing well in low-load oxidation-resistant applications at temperatures up to 1100°C.
