### **Product Introduction: Alloy A-286 / Incoloy A-286 Forgings** **Engineered for Extreme Service: Superior Strength and Structural Integrity** **Incoloy A-286 Forgings** represent the pinnacle of high-strength, high-temperature component manufacturing. As a precipitation-hardenable iron-nickel-chromium superalloy, A-286 is renowned for its exceptional strength and oxidation resistance at temperatures up to 1300°F (704°C). The forging process further enhances these inherent qualities by refining the grain structure, improving mechanical properties, and ensuring maximum structural integrity for the most critical applications in aerospace, power generation, and industrial processing. Our forged components are produced to the highest standards, offering superior resistance to creep, stress rupture, and fatigue compared to cast or fabricated alternatives. --- #### **1. Chemical Composition (Weight %)** The precise composition is the foundation of A-286's performance. | Element | Content (%) | | :--- | :--- | | **Iron (Fe)** | Balance | | **Nickel (Ni)** | 24.0 - 27.0 | | **Chromium (Cr)** | 13.5 - 16.0 | | **Molybdenum (Mo)** | 1.0 - 1.5 | | **Titanium (Ti)** | 1.9 - 2.35 | | **Manganese (Mn)** | 2.0 max | | **Silicon (Si)** | 1.0 max | | **Aluminum (Al)** | 0.35 max | | **Vanadium (V)** | 0.10 - 0.50 | | **Boron (B)** | 0.001 - 0.010 | | **Carbon (C)** | 0.08 max | | **Phosphorus (P)** | 0.025 max | | **Sulfur (S)** | 0.025 max | *Key Strengthening Mechanism:* The age-hardening (precipitation hardening) response is achieved through the formation of the gamma prime phase [Ni₃(Ti, Al)], enabled by the careful balance of **Titanium** and **Aluminum**. --- #### **2. Physical Properties** | Property | Value | | :--- | :--- | | **Density** | 0.290 lb/in³ (7.93 g/cm³) | | **Melting Range** | 2550 - 2600°F (1399 - 1427°C) | | **Specific Heat** | 0.11 Btu/lb-°F (460 J/kg-°K) | | **Thermal Conductivity** | 9.5 Btu-ft/hr-ft²-°F (at 212°F / 100°C) | | **Thermal Expansion Coefficient** | 9.2 x 10⁻⁶ per °F (16.6 x 10⁻⁶ per °K) from 20-1000°F | | **Modulus of Elasticity (Tension)** | 29.5 x 10⁶ psi (203 GPa) | --- #### **3. Mechanical Properties (Typical for Forgings in Age-Hardened Condition)** Forgings are typically supplied in the solution-annealed condition to facilitate machining and are subsequently age-hardened to achieve their ultimate strength. | Property | Solution Annealed | Age-Hardened (Standard) | | :--- | :--- | :--- | | **Tensile Strength, min** | 95 ksi (655 MPa) | 140 ksi (965 MPa) | | **Yield Strength (0.2% Offset), min** | 45 ksi (310 MPa) | 95 ksi (655 MPa) | | **Elongation (in 2"), min** | 35% | 15% | | **Reduction of Area, min** | 35% | 20% | | **Hardness** | Rb 85 | Rc 28 - 38 | *Note:* The forging process typically results in properties at the upper end of these ranges, with excellent toughness and fatigue life. --- #### **4.
