Nickel 200 Nickel Alloy Strip
Product Introduction
Nickel 200 nickel alloy plates are commonly used in chemical equipment (reactors, heat exchangers, chlor-alkali electrolysers), the electronics industry (sputtering targets, battery current collectors), marine engineering (seawater desalination plants, ship pipelines), and aerospace (fuel system components).
Our Nickel 200 nickel alloy plates are produced using advanced smelting processes such as vacuum induction melting (VIM). The Roco Group is a well-known speciality alloy manufacturer with a proven track record of supplying to the chemical and electronics industries. We can also verify their quality system certifications (such as ISO 9001 – Lork Alloy -About Us or contact us to obtain the original documents).
Special Note for High-Temperature Applications: If your components require long-term operation at temperatures above 315°C, please note that carbon in Nickel 200 may precipitate as graphite, leading to material embrittlement. In such cases, the low-carbon version of Nickel 201 (UNS N02201) should be considered. Please get in touch with us for a technical specification sheet or a quote.
Procurement Specifications and Industry Standards
When inquiring about prices and placing orders, Lork Group typically communicates the following details with you:
1. Product Form and Specifications:
Common thicknesses for Nickel 200 alloy plates include cold-rolled plates (generally no more than 2.0mm) and hot-rolled plates (greater than or equal to 4.0mm). Specific available thicknesses, widths, and lengths need to be confirmed with the supplier.
2. Key Standards:
ASTM B162: This is the direct standard for nickel plates, sheets, and strips.GB/T 2054-2023: Chinese standard for nickel and nickel alloy plates.
The standards to be followed should be clearly stated in the purchase contract.
3. Delivery Condition:
Plates may be supplied in hot-rolled, cold-rolled, or annealed conditions, which directly affect their mechanical properties and subsequent processing. This must be clearly specified in the contract.
Manufacturing Process and Challenges
Nickel 200 alloy has good machinability, but there are still some points that require special attention. Whether purchasing raw materials, machining simple parts, or precision-machined parts, the following points should be noted by skilled machining personnel regarding secondary processing:
Cold working:
This alloy tends to work harden; it hardens rapidly during cold rolling, stamping, bending, and other processing. It is essential to strictly control the amount of deformation per pass and to schedule intermediate annealing (usually recrystallisation annealing at 700-900°C) at appropriate times (such as when the deformation is large) to restore the material's plasticity and prevent cracking.
Cutting:
Its material is quite sticky, which may cause tool wear. It is recommended to use rigid equipment and suitable tools and ensure adequate cooling.

Chemical Composition
| Weight% | Alloy 200 |
| Ni | ≥99.0% |
| C | ≤0.15% |
| Fe | ≤0.40% |
| Cu | ≤0.25% |
| Mn | ≤0.35% |
Mechanical Properties
Material properties are greatly affected by the state of supply. Cold-rolled materials have higher strength and hardness, but lower plasticity; annealed materials have good plasticity and are easy to form into complex shapes.
| Material | Annealed sheet |
| Tensile Strength MPa | 380-550 MPa |
| Yield Strength MPa | 120-350 MPa |
| Reduction of Area % | 35-50% |
| Melting point | Between 1435-1446℃ |
Key Points of Quality Inspection Process
To ensure the material quality of the nickel 200 nickel alloy strip, a complete third-party testing report should be requested from the supplier during procurement. Lork Inspection Laboratory's comprehensive testing program lists the following four key testing items:
1. Chemical Composition Analysis: Upon arrival, a spectroscopic analysis (e.g., ICP-OES) should be performed to verify that the composition meets standard requirements.
2. Mechanical Property Testing: Room temperature tensile tests should be conducted to verify that tensile strength, yield strength, and elongation meet standards.
3. Physical Property Testing:
This may include hardness testing and grain size rating (e.g., ASTM 4-7 required).
4. Corrosion Resistance Assessment: For applications with stringent corrosion resistance requirements, corrosion tests in specific media may be required.
