### **Technical Datasheet: Nickel 200 Strip (UNS N02200)** #### **1. Product Overview** **Nickel 200 Strip** (commercially known as **Alloy 200 Strip**) is a thin, flat-rolled product supplied in coiled form, manufactured from commercially pure nickel (99.6% minimum). Characterized by its precise dimensional tolerances and superior surface finish, this product form is specifically designed for applications requiring intricate fabrication and consistent material properties. Nickel 200 Strip maintains excellent corrosion resistance and mechanical properties from cryogenic temperatures up to approximately **315°C (600°F)**. The material's exceptional formability and consistent quality make it ideal for high-volume manufacturing processes. **Temperature Service Note:** For continuous exposure above 315°C (600°F), **Nickel 201 Strip (UNS N02201)** is recommended due to its controlled carbon content that prevents intergranular embrittlement. #### **2.
