### **Product Introduction: Alloy 801 / Incoloy 801 / UNS N08801 Forgings** **Overview** Alloy 801 (Incoloy 801) is a titanium-stabilized nickel-iron-chromium alloy engineered for exceptional high-temperature performance. **Incoloy 801 Forgings** are produced through a controlled process of heating and mechanically deforming the alloy under high pressure, resulting in a superior grain structure that enhances mechanical properties. This forging process provides unmatched strength, structural integrity, and directional toughness, making these components ideal for the most demanding applications in aggressive environments. Forgings are typically supplied as bars, rings, blanks, or near-net-shape parts like valves, flanges, and pump bodies, offering reliability in continuous service up to 1100°C (2012°F). **Key Characteristics of Forgings** * **Superior Mechanical Strength:** The forged grain flow provides higher tensile, yield, and impact strength compared to cast or fabricated components. * **Enhanced Structural Integrity:** The forging process eliminates internal porosity and refines the grain structure, resulting in greater reliability and resistance to fatigue and creep. * **Excellent Directional Properties:** Mechanical properties are more isotropic, providing consistent performance under multi-axial stress. * **Outstanding Oxidation & Carburization Resistance:** Withstands scaling and carbon absorption in high-temperature atmospheres, ensuring long service life. * **Good Weldability:** Can be readily welded to matching or similar alloys for fabricating larger assemblies. --- ### **Chemical Composition (Weight %)** The chemical composition of UNS N08801 forgings conforms to strict international standards to ensure consistent high-temperature performance. | Element | Content (%) | | :--- | :--- | | **Nickel (Ni)** | 30.0 - 34.0 | | **Chromium (Cr)** | 19.0 - 22.0 | | **Iron (Fe)** | Balance | | **Carbon (C)** | 0.05 - 0.10 | | **Titanium (Ti)** | 0.15 - 0.60 | | **Aluminum (Al)** | ≤ 0.30 | | **Manganese (Mn)** | ≤ 1.50 | | **Silicon (Si)** | ≤ 1.00 | | **Copper (Cu)** | ≤ 0.75 | | **Sulfur (S)** | ≤ 0.015 | *The balance is Iron (Fe).
