### **Product Introduction: Alloy X-750 / Inconel X-750 - Other Product Forms & Specifications (UNS N07750)** #### **Overview** **Alloy X-750** (commercially known as **Inconel® X-750**) encompasses a diverse range of specialized product forms beyond standard bars, sheets, and forgings. These "other" specifications include customized shapes, semi-finished products, and specialized configurations tailored for specific industrial applications. These variants maintain the alloy's fundamental characteristics - excellent high-temperature strength up to 700°C (1300°F), good corrosion resistance, and outstanding oxidation resistance - while offering unique advantages for specialized applications in aerospace, nuclear, and industrial sectors. The versatility of Alloy X-750 allows for numerous specialized product forms, each engineered to meet specific performance requirements while maintaining the alloy's signature precipitation-hardening capability through gamma prime [γ'-Ni₃(Al,Ti)] phase formation. --- #### **Chemical Composition** The chemical composition remains consistent across all special product forms: | Element | Content (%) | |---------|-------------| | **Nickel (Ni)** | 70.0 minimum | | **Chromium (Cr)** | 14.0 - 17.0 | | **Iron (Fe)** | 5.0 - 9.0 | | **Titanium (Ti)** | 2.25 - 2.75 | | **Copper (Cu)** | 0.50 maximum | | **Aluminum (Al)** | 0.40 - 1.00 | | **Niobium (Nb)** | 0.70 - 1.20 | | **Carbon (C)** | 0.08 maximum | | **Manganese (Mn)** | 1.00 maximum | | **Silicon (Si)** | 0.50 maximum | | **Sulfur (S)** | 0.01 maximum | --- #### **Physical Properties** Consistent physical properties across all product forms: | Property | Metric Value | Imperial Value | |----------|--------------|----------------| | **Density** | 8.28 g/cm³ | 0.298 lb/in³ | | **Melting Range** | 1390 - 1430 °C | 2530 - 2600 °F | | **Specific Heat (20°C)** | 431 J/kg·K | 0.103 Btu/lb·°F | | **Thermal Conductivity (20°C)** | 11.8 W/m·K | 81.9 Btu·in/hr·ft²·°F | | **Thermal Expansion Coefficient (20-100°C)** | 12.8 μm/m·°C | 7.1 μin/in·°F | | **Modulus of Elasticity** | 214 GPa | 31.0 x 10⁶ psi | | **Electrical Resistivity** | 1.22 μΩ·m | - | --- #### **Specialized Product Forms & Applications** **1.
