ASTM B160 Nickel Alloy 200 Rod

ASTM B160 Nickel Alloy 200 Rods are round bars with nickel as the base material (usually ≥99.5%), and are classified into ordinary and low-carbon versions according to carbon content.

Pure nickel bar means a solid, long bar made of high-purity metallic nickel.
Nickel content is generally ≥99.0%, commonly US standards 201 and 200.
Appearance: silvery-white metal, rust-resistant, tough, and relatively soft.
Shape: round bars are the most common, but square and hexagonal bars also exist.

Extremely alkali resistant: Almost non-corrosive in caustic soda and strong alkaline environments, making it a "alkali-resistant wonder" in the chemical industry.
Corrosion resistant: Stable in neutral and weakly corrosive environments.
Good plasticity: Easy to process, bend, and weld.
Good electrical and thermal conductivity: Commonly used in electrodes and electronic components.
Magnetic: Can be attracted by magnets at room temperature.

1. Basic physical parameters: Density 8.90 g/cm³; Melting point 1455℃; Thermal conductivity at room temperature approximately 90 W/(m・K); Resistivity approximately 9.6 μΩ・cm; Paramagnetic, weakly magnetic at room temperature; Moderate coefficient of linear expansion, good dimensional stability.
2. Core advantages of corrosion resistance: Extremely strong resistance to hot concentrated alkali solutions (NaOH/KOH), making it the first choice for the alkali production industry; Stable in neutral salt, carbonate, and acetate environments; Performs well against reducing acids and organic acids; However, caution is required in strong oxidizing acids (such as concentrated nitric acid) and chlorine-containing oxidizing media; Easily forms a dense oxide film on the surface, protecting the substrate.
3. Mechanical properties (typical values ​​in the annealed state)

***The strength can be significantly improved after cold working (e.g., the tensile strength in the cold working state can reach 650+ MPa), while the elongation decreases; the plasticity can be restored by annealing; it has excellent low-temperature toughness and no brittle transition problem.

A.Supply Conditions and Specifications:

Conditions: Soft (M, fully annealed), semi-hard, hard (Y, cold-worked);

Diameter: Standard Φ3 mm~150 mm, precision fine bars up to Φ0.8 mm, large forged rounds up to Φ450 mm; Lengths are mostly 1000 mm, 2000 mm, 3000 mm, custom lengths available upon request;

Surface: Black skin (hot rolled), pickled, bright drawn (cold drawn).

B.Manufacturing process:

Electrolytic nickel plate → Vacuum induction/arc melting → Forging billet → Hot rolling/hot extrusion → Cold drawing/cold rolling finishing → Solution annealing → Non-destructive testing, precision cutting, and packaging; High-end pure nickel bars adopt electron beam/vacuum arc remelting (VAR) to further reduce impurities and segregation.

1. Chemicals/Chlor-alkali: Caustic soda evaporators, alkali storage tanks, electrolytic cell electrodes, pipe fittings;
2. Electronics/Electroplating: Vacuum tubes, cathodes, electroplating anodes, battery terminals;
3. Energy/Nuclear Power: Nuclear reactor control rod components, hydrogen fuel cell bipolar plates;
4. Food/Pharmaceuticals: Corrosion-resistant containers, sterile pipes, pharmaceutical equipment parts;
5. Marine/Environmental Protection: Seawater desalination equipment, water treatment corrosion-resistant components;
6. Welding Materials: Raw materials for pure nickel welding rods/wires.
