IN 100 UNS N13100 Centri-Vac Nickel Based Alloy,Cast UNS N13100; 1

### **Product Introduction: INCONEL® 100 (IN 100) UNS N13100 Centri-Vac Nickel-Based Superalloy** **Overview** INCONEL® 100 (commonly designated IN 100, IN-100, or IN100) is a high-strength, precipitation-hardenable nickel-based superalloy developed specifically for advanced gas turbine applications. When produced using the "Centri-Vac" process—which combines centrifugal casting with vacuum melting—it achieves exceptional metallurgical quality, homogeneity, and performance. This alloy is characterized by its excellent high-temperature strength, outstanding creep resistance, and superior fatigue properties, making it ideal for critical rotating components in aerospace and industrial gas turbines operating at temperatures up to 980°C (1800°F). --- #### **Chemical Composition (Typical % by Weight)** The composition of IN 100 is optimized for high-volume fraction gamma prime (γ') strengthening. | Element | Content (%) | Role & Benefit | | :--- | :--- | :--- | | **Nickel (Ni)** | Balance | Forms the austenitic (gamma) matrix. | | **Cobalt (Co)** | 13.0 - 17.0 | Enhances high-temperature strength and microstructural stability. | | **Chromium (Cr)** | 8.0 - 10.0 | Provides oxidation and hot corrosion resistance. | | **Aluminum (Al)** | 4.5 - 5.5 | Primary gamma prime (γ') former (Ni₃Al). | | **Titanium (Ti)** | 4.5 - 5.0 | Secondary gamma prime (γ') former (Ni₃Ti). | | **Molybdenum (Mo)** | 2.5 - 3.5 | Solid-solution strengthener. | | **Vanadium (V)** | 0.8 - 1.2 | Enhages strength and stability. | | **Carbon (C)** | 0.10 - 0.20 | Forms primary and grain boundary carbides for strength. | | **Boron (B)** | 0.010 - 0.025 | Strengthens grain boundaries. | | **Zirconium (Zr)** | 0.03 - 0.09 | Enhages creep rupture life and ductility. | *Note: "INCONEL" and "IN 100" are trademarks of Special Metals Corporation.
