### **Technical Datasheet: Nickel 201 - Other Specifications & Equivalent Grades (UNS N02201)** #### **1. Overview** **Nickel 201** (UNS N02201) is recognized globally under various national and international standards as the low-carbon version of commercially pure nickel. While maintaining the fundamental corrosion resistance and physical properties of nickel, the controlled carbon content (0.02% max) makes it suitable for high-temperature applications where Nickel 200 would be susceptible to embrittlement. This document outlines the equivalent specifications and specialized standards for Nickel 201 across different regions and industries. #### **2. Chemical Composition (% Weight)** The base composition is consistent across major specifications, with the key distinction being the controlled low carbon content. | Element | ASTM B160/162/163 | ASME SB-160/162/163 | DIN 17740 | ISO 6208 | | :--- | :--- | :--- | :--- | :--- | | **Nickel (Ni)** | 99.0 min | 99.0 min | 99.0 min | 99.0 min | | **Carbon (C)** | **0.02 max** | **0.02 max** | **0.02 max** | **0.02 max** | | **Manganese (Mn)** | 0.35 max | 0.35 max | 0.30 max | 0.35 max | | **Iron (Fe)** | 0.40 max | 0.40 max | 0.40 max | 0.40 max | | **Copper (Cu)** | 0.25 max | 0.25 max | 0.20 max | 0.25 max | | **Silicon (Si)** | 0.35 max | 0.35 max | 0.30 max | 0.35 max | | **Sulfur (S)** | 0.01 max | 0.01 max | 0.01 max | 0.01 max | #### **3.
