### **Technical Datasheet: Nickel 200 Plate (UNS N02200)** #### **1. Product Overview** **Nickel 200 Plate** (commercially known as **Alloy 200 Plate**) is a wrought product form manufactured from commercially pure nickel (99.6% minimum). This plate material offers exceptional corrosion resistance, excellent mechanical properties, and high thermal and electrical conductivity, making it suitable for demanding industrial applications. Available in various thickness ranges, Nickel 200 Plate maintains its structural integrity and corrosion resistance from cryogenic temperatures up to approximately **315°C (600°F)**. The material exhibits good forming and welding characteristics, allowing for fabrication into complex vessels and components. **High-Temperature Notice:** For sustained service above 315°C (600°F), **Nickel 201 Plate (UNS N02201)** is recommended due to its lower carbon content, which prevents embrittlement from grain-boundary carbide precipitation. #### **2. Chemical Composition (% Weight)** Composition conforms to ASTM B162 standard for nickel plate, sheet, and strip. | Element | Content (%) (ASTM B162) | Content (%) (Typical) | | :--- | :--- | :--- | | **Nickel (Ni)** | 99.0 min | ≥ 99.6 | | **Carbon (C)** | 0.15 max | 0.08 | | **Manganese (Mn)** | 0.35 max | 0.20 | | **Iron (Fe)** | 0.40 max | 0.20 | | **Copper (Cu)** | 0.25 max | 0.15 | | **Silicon (Si)** | 0.35 max | 0.15 | | **Sulfur (S)** | 0.01 max | 0.005 | #### **3.
