ASTM Premium Pure Nickel Rod UNS N02200 N02201 Nickel 200 201
Premium Pure Nickel Rods (UNS N02200/N02201): Engineered for Extreme Performance in Hostile Environments
Pure Nickel Rods, compliant with UNS N02200 (Nickel 200) and N02201 (Nickel 201) standards, redefine reliability in applications demanding unwavering resistance to aggressive chemical attack, superior thermal/electrical efficiency, and structural stability across a staggering -200°C to +600°C operational range. Precision-crafted for industries where material failure is not an option, these rods excel in:
-
Aerospace & Defense: Cryogenic fuel transfer systems, rocket engine components, and satellite thermal management.
-
Advanced Chemical Processing: Caustic soda (NaOH) reactors, chlorine gas handling, and sulfuric acid (≤80% concentration) equipment.
-
High-Precision Electronics: Semiconductor fabrication tools, ultra-conductive battery terminals, and EMI/RF shielding solutions.

Technical Q&A
Q1: Why choose Nickel 201 over Nickel 200 for high-temperature applications?
A: Nickel 201 (UNS N02201) has a lower carbon content (≤0.02%), reducing embrittlement risks above 315°C. Ideal for furnace components and heat-treating equipment.
Q2: Can pure nickel rods withstand hydrochloric acid (HCl)?
A: No. Pure nickel excels in alkaline and neutral environments but is unsuitable for HCl. Consider Hastelloy® C276 for acidic media.
Q3: What standards govern pure nickel rod manufacturing?
A: ASTM B160 (rod/bar), B161 (tube), and ASME SB-160/SB-161. Certifications include NACE MR0175 for sour service.
