Description (English)
Inconel 601 (UNS N06601 / Werkstoff 2.4851) is a nickel-chromium-iron solid-solution alloy containing approximately 60% nickel, 23% chromium, and 1.4% aluminum. The aluminum addition combined with the high chromium content gives the alloy outstanding resistance to oxidation, carburization, and sulfidation at temperatures up to 1250 Β°C, particularly under cyclic thermal conditions. The alloy retains excellent mechanical strength, creep resistance, and metallurgical stability across a wide temperature range, and resists chloride-ion stress-corrosion cracking. Inconel 601 is a standard workhorse material for industrial furnaces, heat-treating equipment, chemical process heaters, radiant tubes, and petrochemical components where long-term high-temperature performance is required.
