### **Product Datasheet: Alloy 450 / Monel® 450 Rod** **A High-Strength, Corrosion-Resistant Nickel-Copper Alloy Rod for Demanding Applications** --- #### **Overview** Alloy 450 (Monel 450) Rod is a non-age-hardenable nickel-copper alloy supplied in round, hexagonal, or square bar form. It is engineered to provide an excellent combination of high strength, exceptional toughness, and superior corrosion resistance in a wide range of environments, from seawater to chemical process streams. The rod form is specifically produced for machining into critical components like shafts, fasteners, and valve trim, where reliability and longevity are paramount. Its immunity to chloride-induced stress corrosion cracking and good machinability make it a preferred material for demanding applications in marine, oil and gas, and chemical processing industries. --- #### **Key Features & Advantages** * **Excellent Corrosion Resistance:** Offers robust resistance to seawater, sulfuric and hydrofluoric acids, alkaline solutions, and other corrosive media. * **High Strength and Toughness:** Provides a superior balance of tensile strength and impact resistance, even at sub-zero temperatures. * **Immunity to Chloride Stress Corrosion Cracking:** A key advantage over many austenitic stainless steels, ensuring reliability in chloride-containing environments. * **Good Machinability:** Can be machined to precise tolerances, producing clean, continuous chips. Its machinability rating is comparable to that of Alloy 400. * **Good Weldability:** Can be readily welded using common techniques such as Gas Tungsten Arc Welding (GTAW/TIG) and Gas Metal Arc Welding (GMAW/MIG). * **Non-Magnetic:** Exhibits non-magnetic properties in all conditions. --- #### **Chemical Composition (Weight % - Typical)** The composition is balanced for optimal performance in wrought bar products. | Element | Content (%) | | :--- | :--- | | **Nickel (Ni)** | 63.0 - 70.0 | | **Copper (Cu)** | 26.0 - 33.0 | | **Iron (Fe)** | 2.0 - 3.0 | | **Manganese (Mn)** | 1.5 max | | **Carbon (C)** | 0.3 max | | **Silicon (Si)** | 0.5 max | | **Sulfur (S)** | 0.024 max | --- #### **Physical Properties** | Property | Value / Condition | | :--- | :--- | | **Density** | 8.80 g/cm³ (0.318 lb/in³) | | **Melting Point** | 1350 - 1400 °C (2460 - 2550 °F) | | **Electrical Resistivity** | ~51 μΩ·cm at 20°C | | **Thermal Conductivity** | ~21.8 W/m·K at 20°C | | **Thermal Expansion Coefficient** | 14.2 μm/m·K (20-100°C) | | **Modulus of Elasticity** | 179 GPa (26 x 10⁶ psi) | | **Magnetic Permeability** | **~1.0** (Essentially non-magnetic) | --- #### **Mechanical Properties (Typical for Rod)** Properties vary with diameter and temper (hot finished, cold drawn, annealed). **Room Temperature Properties (Hot Finished, Annealed)** * **Tensile Strength:** 550 - 690 MPa (80 - 100 ksi) * **Yield Strength (0.2% Offset):** 240 - 380 MPa (35 - 55 ksi) * **Elongation (in 4D):** 35 - 45% **Room Temperature Properties (Cold Drawn, As-Drawn)** * **Tensile Strength:** 620 - 760 MPa (90 - 110 ksi) * **Yield Strength (0.2% Offset):** 480 - 620 MPa (70 - 90 ksi) * **Elongation (in 4D):** 15 - 25% --- #### **International Standards** Alloy 450 Rod conforms to several key international standards. * **ASTM (USA):** * **ASTM B164:** Standard Specification for Nickel-Copper Alloy Rod, Bar, and Wire. * **UNS (Unified Numbering System):** **N05500** *Note: It is critical to specify the non-age-hardenable requirement, as UNS N05500 is also used for the chemistry of Monel K-500. The distinction is made by the heat treatment (or lack thereof) and the mechanical properties ordered.* * **ASME (American Society of Mechanical Engineers):** **SB-164** * **DIN (Germany):** **2.4370** * **ISO (International Organization for Standardization):** Can be supplied to equivalent ISO specifications upon request. --- #### **Product Applications** Alloy 450 Rod is the starting material for numerous high-performance components. * **Pump and Valve Shafts:** Used in centrifugal pumps and valves handling seawater, brines, and corrosive chemicals. * **Fasteners:** Corrosion-resistant bolts, studs, nuts, and screws for marine and chemical processing equipment. * **Marine Components:** Propeller shafts, rudder stocks, and other critical naval architecture parts. * **Oil & Gas Industry:** Non-magnetic drill collar components, tool joints, and downhole instrumentation housings in sour service (H₂S) environments. * **Chemical Processing:** Agitator shafts, stem for control valves, and other machined parts exposed to acids and alkalis. * **Power Generation:** Bolting, studs, and other components in feedwater and heat exchanger systems. --- #### **Fabrication Notes** * **Machining:** Machines similarly to Monel 400. Use positive rake angles, rigid setups, and sharp tools. Recommended speeds are slightly lower than for steel. * **Welding:** Highly weldable. Use Monel 60 or 67 filler metal. Preheating is not required. Post-weld heat treatment is generally not necessary for this non-age-hardenable grade. * **Forging:** Forging temperature range is 1050 - 1150°C (1920 - 2100°F). --- **Disclaimer:** *Monel® is a registered trademark of Special Metals Corporation (a PCC company).* The information provided is typical and for reference purposes. Mechanical properties are dependent on rod diameter and temper. It is essential to confirm with the supplier that the product supplied meets the specific requirements for the non-age-hardenable grade of Alloy 450 rod for your application.
