Inconel 601 contains nearly 58–63% nickel, 21–25% chromium, and 1–1.7% aluminum, the rest being primarily iron. The aluminum addition improves high-temperature oxidation resistance, whereas the general composition ensures structural integrity at 1200°C (2200°F). The alloy offers tensile strength of approximately 650–750 MPa, yield strength of approximately 300 MPa, and elongation of 30–45%. It also has superior resistance against carburization, nitridation, and spalling in high-heat applications and can be used in severe thermal cycling service.
