ASTM B160 Nickel Rod: Applications and Selection Requirements
- ASTM B160 Nickel Rod
ASTM B160 specifies nickel rod and bar. Nickel 200 and Nickel 201 can be evaluated for chemical-process and electrical components when their grade, condition and properties meet the actual design. Material suitability must be assessed for the service environment and the finished component.
Grade and specification
Nickel 200 is UNS N02200; Nickel 201 is the low-carbon grade UNS N02201. ASTM B160 covers rod and bar, with requirements that depend on grade and condition. Specify the applicable edition, shape, dimensions and tolerances, condition, surface, quantity and the inspection records required for the order. Use the contracted standard and supplied-lot documents for acceptance values.
Applications and operating conditions
Nickel rod may be considered for components in chemical processing or electrical assemblies. Selection depends on medium, concentration, temperature, contaminants, loading, fabrication and electrical requirements. Corrosion resistance in one chemical environment does not establish resistance to all acids, salts or mixed media.
Nickel 200 is ferromagnetic at ordinary temperatures; assess the actual magnetic response where it matters to the component. The Special Metals Nickel 200 and 201 data sheet notes a preference for Nickel 201 above 315 °C because of Nickel 200’s susceptibility to graphitization at elevated temperature. This guidance is not a blanket approval or temperature guarantee for any rod or installation.
Inspection, traceability and regulated uses
| Topic | Order-specific information |
|---|---|
| Material | UNS grade, standard edition, bar shape and condition. |
| Dimensions | Diameter or section, length, tolerance and surface. |
| Testing | Required chemistry, mechanical tests and any supplementary inspection. |
| Documents | Material identification, traceability and agreed records. |
For food contact, medical or other regulated uses, determine applicable requirements and test the finished component as necessary. A material grade or certificate alone does not prove absence of nickel release or establish regulatory approval.
Frequently asked questions
Does ASTM B160 specify nickel wire?
It covers rod and bar; identify a suitable wire specification separately.
Are Nickel 200 and 201 interchangeable in every service?
No. Evaluate chemistry, temperature, condition and the application requirements.
