### **Product Introduction: Alloy WE132 / INCONEL WE132 & Equivalent Specifications** **Alloy WE132** is a historical designation that is fundamentally equivalent to the widely recognized nickel-based superalloy **INCONEL 718**. The "WE132" nomenclature is primarily associated with its use as a welding electrode or filler metal. However, the wrought product forms (bar, wire, plate, sheet) made to this composition are globally standardized as **INCONEL 718 (UNS N07718)**. This alloy is a precipitation-hardenable nickel-chromium material containing significant amounts of niobium and molybdenum. It is one of the most used superalloys due to its unique combination of high strength, excellent fatigue and creep resistance, and good fabricability, especially its outstanding weldability and resistance to post-weld cracking. --- #### **Key Features & Advantages** * **Multi-Purpose Superalloy:** Serves as a base metal (plate, bar, forgings), a filler metal (welding wire), and a casting alloy. * **Excellent Strength Over a Wide Temperature Range:** Exhibits exceptionally high yield, tensile, and creep-rupture properties from **cryogenic temperatures up to 700°C (1300°F)**. * **Superior Weldability:** Unlike many other age-hardenable superalloys, it is highly weldable without significant susceptibility to strain-age cracking post-weld. * **Outstanding Corrosion Resistance:** Resists a wide variety of corrosive media, including oxidation, pitting, crevice corrosion, and stress-corrosion cracking. * **Age-Hardenable:** Achieves its maximum strength through a precise precipitation hardening heat treatment. --- #### **Chemical Composition (Typical Weight %)** The core composition remains consistent across product forms, as defined by UNS N07718. | Element | Content (%) | Element | Content (%) | | :--- | :--- | :--- | :--- | | **Nickel (Ni)** | 50 - 55 | **Molybdenum (Mo)** | 2.8 - 3.3 | | **Chromium (Cr)** | 17 - 21 | **Aluminum (Al)** | 0.2 - 0.8 | | **Iron (Fe)** | Balance | **Titanium (Ti)** | 0.65 - 1.15 | | **Niobium (Nb)** | 4.75 - 5.5 | **Carbon (C)** | ≤ 0.08 | | **Manganese (Mn)** | ≤ 0.35 | **Silicon (Si)** | ≤ 0.35 | | **Cobalt (Co)** | ≤ 1.0 | **Sulfur (S)** | ≤ 0.015 | | **Boron (B)** | ≤ 0.006 | **Copper (Cu)** | ≤ 0.30 | --- #### **Physical Properties** | Property | Metric Unit | Imperial Unit | | :--- | :--- | :--- | | **Density** | 8.19 g/cm³ | 0.296 lb/in³ | | **Melting Range** | 1260 - 1336 °C | 2300 - 2440 °F | | **Specific Heat (20°C)** | 435 J/kg·K | 0.104 Btu/lb·°F | | **Thermal Conductivity** | 11.4 W/m·K (100°C) | 79 Btu·in/hr·ft²·°F (212°F) | | **Thermal Expansion Coefficient** | 13.0 μm/m·°C (20-100°C) | 7.2 x10⁻⁶ in/in·°F (68-212°F) | | **Modulus of Elasticity** | 200 GPa | 29 x 10⁶ psi | --- #### **Mechanical Properties (Typical for Solution Annealed & Aged Condition)** *Properties are representative for bar and plate; exact values vary by product form and specific heat treatment.* | Property | Value (Metric) | Value (Imperial) | | :--- | :--- | :--- | | **Tensile Strength, Ultimate** | ≥ 1275 MPa | ≥ 185 ksi | | **Tensile Strength, Yield (0.2% Offset)** | ≥ 1035 MPa | ≥ 150 ksi | | **Elongation at Break** | ≥ 12 % | ≥ 12 % | | **Hardness (Rockwell C)** | 35 - 44 HRC | 35 - 44 HRC | --- #### **International & Cross-Industry Standards** Alloy WE132 / INCONEL 718 is covered by a vast array of international specifications, which is a testament to its importance. **Common Wrought Product Standards (Bar, Sheet, Plate, Strip, Tube):** * **ASTM B637:** Precipitation-Hardening Nickel Alloy Bars, Forgings, and Forging Stock. * **ASTM B670:** Age-Hardening Nickel Alloy Plate, Sheet, and Strip. * **AMS 5662:** Nickel Alloy, Corrosion and Heat-Resistant, Bars, Forgings, and Rings. * **AMS 5596:** Nickel Alloy, Corrosion and Heat-Resistant, Sheet, Strip, and Plate. **Welding Product Standards (the origin of "WE132"):** * **AWS A5.11 / ASME SFA-5.11:** ENiCrFe-7 (Classification for nickel-alloy welding electrode). * **AWS A5.14 / ASME SFA-5.14:** ERNiFeCr-7 (Classification for nickel-alloy filler metal). **Other National & International Standards:** * **UNS:** N07718 * **DIN / EN:** 2.4668 (Material No. 2.4668) * **ISO:** 15156-3 / NACE MR0175: Approved for use in sour service (H₂S-containing) environments in oil and gas production. * **GOST:** ХН55МВФК (Russian equivalent). --- #### **Product Applications** The versatility of this alloy allows it to be used in numerous critical applications across all high-performance industries. * **Aerospace:** * **Base Metal:** Jet engine turbine discs, blades, shafts, casings, afterburners. * **Welding:** Repair and fabrication of engine components and airframes. * **Oil & Gas:** * **Base Metal:** Downhole tools, wellhead components, valve bodies, fasteners for sour service. * **Welding:** Cladding of wellheads and Christmas trees, fabrication of pipelines and vessels. * **Power Generation:** * **Base Metal:** Gas turbine blades, discs, bolts, and critical components in nuclear reactors. * **Chemical Processing:** * **Base Metal:** Reactors, heat exchangers, and vessels handling corrosive chemicals. * **Automotive & Motorsport:** * Turbocharger wheels, high-performance engine valves. --- **Disclaimer:** *INCONEL® is a registered trademark of Special Metals Corporation.
