### **Product Introduction: Alloy 400 / Monel 400 Plate** #### **Overview** Alloy 400, commonly known under the trade name Monel® 400, is a nickel-copper alloy renowned for its exceptional corrosion resistance in a wide range of environments. It exhibits high strength and toughness, excellent performance in seawater and various chemical media, and good weldability. Our Monel 400 plates are manufactured to the highest international standards, providing reliable performance for demanding applications across multiple industries. *(Note: "Monel 450" is not a standard designation. The correct and widely recognized name for this specific nickel-copper alloy is Monel 400 or UNS N04400. Alloy 450 typically refers to a different material, a ferritic stainless steel. This introduction assumes the intended material is the nickel-copper alloy Monel 400.)* --- #### **Key Features & Advantages** * **Excellent Corrosion Resistance:** Performs exceptionally well in seawater, sulfuric and hydrochloric acids, and alkaline solutions. * **High Strength & Toughness:** Maintains mechanical properties across a wide temperature range, from cryogenic to elevated temperatures (~1000°F / 538°C). * **Low Corrosion Rate in Flowing Seawater:** Highly resistant to chloride-ion stress-corrosion cracking and erosion-corrosion. * **Good Fabricability:** Can be welded and fabricated using standard techniques. --- #### **Chemical Composition (Typical % Weight)** The superior properties of Monel 400 are derived from its balanced chemical composition. | Element | Content (%) | | :--- | :--- | | **Nickel (Ni)** | 63.0 min | | **Copper (Cu)** | 28.0 - 34.0 | | **Iron (Fe)** | 2.5 max | | **Manganese (Mn)** | 2.0 max | | **Carbon (C)** | 0.3 max | | **Silicon (Si)** | 0.5 max | | **Sulfur (S)** | 0.024 max | *Note: Ni + Cu ≥ 63.0% min.* --- #### **Physical Properties** | Property | Value | | :--- | :--- | | **Density** | 8.80 g/cm³ (0.318 lb/in³) | | **Melting Point** | 1350 °C (2460 °F) | | **Specific Heat** | 427 J/kg·K (0.102 Btu/lb·°F) at 20°C | | **Thermal Conductivity** | 21.8 W/m·K (151 Btu·in/hr·ft²·°F) at 20°C | | **Electrical Resistivity** | 51.0 μΩ·cm at 20°C | | **Magnetic Response** | Essentially non-magnetic at room temperature | --- #### **Mechanical Properties (Typical for Plate)** Properties can vary based on heat treatment and thickness. | Property | Annealed Condition | | :--- | :--- | | **Tensile Strength** | 550 - 690 MPa (80 - 100 ksi) | | **Yield Strength (0.2% Offset)** | 240 - 345 MPa (35 - 50 ksi) | | **Elongation (in 2")** | 35 - 45 % | | **Hardness (Rockwell B)** | 65 - 85 HRB | --- #### **International Standards** Our Monel 400 plates conform to the following international specifications, ensuring global quality and interoperability. | Standard | Plate / Sheet / Strip Form | | :--- | :--- | | **ASTM (USA)** | ASTM B127 | | **ASME (USA)** | ASME SB-127 | | **UNS** | UNS N04400 | | **EN (Europe)** | EN 2.4360 / NiCu30Fe | | **DIN (Germany)** | DIN 17743 / NiCu30Fe | | **JIS (Japan)** | JIS NW 4400 | --- #### **Product Applications** Monel 400 plate is the material of choice for critical components in corrosive environments.
