PRODUCT OVERVIEW
About Nickel 200 / 201 Welding Wire
Nickel 200 / 201 welding wire covers the filler metals classified for joining UNS N02200 and N02201 base metal. The bare product runs as ERNi-1 per AWS A5.14, and the covered electrode runs as ENi-1 per AWS A5.11.
We supply Nickel 200 / 201 welding wire as straight TIG rods, wound MIG spools and sealed electrode packs. Titanium carried by the filler ties up free carbon in the deposit, which keeps the weld sound on grade 201 base metal.
Meanwhile, the base-metal chemistry behind this welding wire sits on our Nickel 200 / 201 material page for weld procedure work.
PRODUCT FEATURES
Key Features of Nickel 200 / 201 Welding Wire
Nickel 200 / 201 welding wire is supplied in UNS N02200 or N02201, the commercially pure grades that hold 99.0% nickel and above. We provide ASTM B160 and ASME SB160 welding wire as ERNi-1 bare wire, TIG rods and MIG spools for caustic plants, chlor-alkali works and electrochemical lines. Every Nickel 200 / 201 welding wire order carries heat-number traceability, EN 10204 3.1 mill test reports and export documentation.

TECHNICAL INFORMATION
Technical Specifications
Detailed technical information including chemical composition, mechanical properties, standards and available dimensions.
Chemical Composition
UNS N02200 and N02201 share one nickel balance of 99.0% minimum, and the carbon ceiling alone separates the two grades inside this welding wire, at 0.15% for grade 200 against 0.02% for grade 201. Above all, that carbon gap decides how far this welding wire can run in hot service.
For an element-by-element account of every limit, open the composition breakdown held on the Nickel 200 / 201 material page for this welding wire.
