Inconel 601 (2.4851) is a nickel-chromium-iron alloy with added aluminum. Its high chromium and aluminum content creates a strong oxide layer at high temperatures, ensuring excellent oxidation and carburization resistance. Additionally, it resists stress corrosion cracking in carburizing conditions and performs well in oxidizing, sulfur-rich environments.Alloy 601 uses solution hardening to maintain superior mechanical properties at both room and elevated temperatures.
Chemical Composition of Inconel 601
| Element | Ni | Cr | Fe | Al | C | Mn | Si | Cu | S |
|---|---|---|---|---|---|---|---|---|---|
| Content (%) | 58.0-63.0 | 21.0-25.0 | Balance | 1.0-1.7 | ≤0.10 | ≤1.0 | ≤0.5 | ≤1.0 | ≤0.015 |
Core Advantages of Inconel 601
Higher levels of chromium and aluminum allow it to thrive in extreme heat. These elements form a dense oxide layer that prevents oxidative damage. It ensures the durability of furnace components and gas turbines.
Carburizing causes carbon to penetrate the surface, which makes the material brittle. Alloy 601’s nickel-rich alloy stops this process, maintaining strength and flexibility. It excels in petrochemical and heat treating equipment.
Stress corrosion cracking consists of a combination of stress and corrosion forming dangerous cracks. The balance of nickel and chromium resists this.
Inconel 601 retains its strength and toughness at temperatures as low as 1200°C. It has a tensile strength of over 550 MPa and resists distortion. Its tensile strength of more than 550 MPa prevents deformation. It provides consistent performance at different temperatures to ensure stability.
