Nickel Alloy Fasteners Supplier
MT.BOLTS manufactures Nickel Alloy fasteners using commercially pure wrought nickel grades such as Nickel 200 (UNS N02200) and Nickel 201 (UNS N02201). These fasteners are known for their excellent mechanical strength, superior resistance to caustic alkalis, and outstanding thermal and electrical conductivity. They are widely used in chemical processing, electronic components, food handling, and marine applications.
Our NICKEL 200 / 201 Fasteners Have the Following Specifications:
- Diameter: M3 to M48 | #4 to 2″
- Length: 6mm to 300mm | 0.25″ to 12″
- Thread Pitch: Metric (Coarse/Fine) | UNC/UNF
- Standards: ASME B18.2.1, ASME B18.3, ASME B18.2.2, DIN/ISO/EN (e.g., DIN 933, DIN 934)
- Material Specifications: ASTM B160, ASTM F2281, ASTM B564 (Nickel 200 / 201)
- Types: Bolts, Screws, Nuts, Washers, Studs
We regularly supply Nickel alloy fasteners and bolts made from high-purity grades Nickel 200 (UNS N02200) and Nickel 201 (UNS N02201). Below are their chemical compositions and mechanical properties for your procurement reference.
Nickel Alloy Fasteners Chemical Composition
| Element | Nickel (Ni) | Carbon (C) | Iron (Fe) | Manganese (Mn) | Silicon (Si) | Sulfur (S) | Copper (Cu) |
| Nickel 200 (UNS N02200) | ≥99.0 | ≤0.15 | ≤0.40 | ≤0.35 | ≤0.35 | ≤0.01 | ≤0.25 |
| Nickel 201 (UNS N02201) | ≥99.0 | ≤0.02 | ≤0.40 | ≤0.35 | ≤0.35 | ≤0.01 | ≤0.25 |
Main difference: Carbon content—Nickel 201 has lower carbon, offering better resistance to intergranular attack at elevated temperatures.

Reasons to Choose Nickel Alloy Fasteners
Nickel 200 and 201 fasteners are made from commercially pure nickel, offering outstanding resistance to a wide range of corrosive environments—particularly caustic alkalis, neutral and alkaline salt solutions, and dry fluorine gas. They feature excellent thermal and electrical conductivity, good ductility, and stability under both low and moderately elevated temperatures. Nickel 201, with lower carbon content than Nickel 200, provides superior performance in applications where intergranular corrosion and graphitization at high temperatures are concerns. These fasteners are ideal where purity, corrosion resistance, and conductivity are critical.

Application of Nickel Alloy Fasteners
- Chemical Processing Equipment – Heat exchangers, reactors, storage vessels handling caustic solutions
- Electronics and Battery Manufacturing – For terminals, connectors, and other high-conductivity parts
- Marine and Offshore – Components exposed to seawater and saline environments
- Food Processing – Due to their non-toxic and non-reactive properties
- Aerospace and Nuclear – Cryogenic and high-purity gas systems
- Salt Production Plants – Brine handling and evaporators
FAQ About Nickel Alloy Fasteners and Bolts
Nickel 201 contains lower carbon (≤0.02%) than Nickel 200 (≤0.15%), making it better suited for high-temperature environments to avoid embrittlement from graphitization.
Yes. They are highly resistant to caustic alkalis, neutral salts, dry gases like fluorine, and mild reducing media.
Yes. Nickel 201 is preferred for elevated temperatures up to around 600 °C (1110 °F), while Nickel 200 is suitable for lower temperature applications.
No, Nickel 200 and 201 are non-magnetic in annealed condition, which is beneficial in sensitive applications.
Yes. Both grades have excellent electrical conductivity, making them suitable for electrical and electronic components.
