Product Description
1. Material Properties
- Strong corrosion resistance: Made of high-quality stainless steel (such as 304, 316, 316L, etc.), it can resist the corrosion of electrolyte (often containing sulfuric acid, chloride ions, etc.), and has a long service life.
- High electrical conductivity: The surface is usually specially treated (such as polishing, coating) to reduce contact resistance and improve current efficiency.
- High mechanical strength: Stainless steel has good rigidity, is not easy to deform, and can withstand mechanical stress during hoisting, transportation, and stripping.
2. Structural Design Features
- High flatness requirement: The surface of the plate is extremely flat (the tolerance is usually ≤ ±2mm/m²), ensuring uniform metal deposition and avoiding short circuits or local over-thickness.
- Optimized edge sealing: The edges are designed with flanging or sealing to prevent the deposited metal from wrapping around the edges, facilitating stripping.
- Robust lifting lug structure: The lifting lugs are firmly welded to the plate body with a reasonable design, facilitating hoisting by crane and stripping operations.

Frequently Asked Questions (FAQ)
What grades of stainless steel are typically used for cathode plates?
Permanent stainless steel cathodes are usually made of high-quality grades such as 304, 316, and 316L. These materials provide strong corrosion resistance against aggressive electrolytes often containing sulfuric acid and chloride ions.
Why is high flatness tolerance critical for cathode plates?
A high flatness tolerance (usually ≤ ±2mm/m²) ensures uniform metal deposition across the plate. This avoids short circuits and prevents local over-thickness of the deposited metal, ensuring a highly efficient electrolysis process.
How do these cathode plates contribute to energy savings?
Thanks to their high electrical conductivity and optimized surface treatments (like conductive coatings and polishing), they reduce contact resistance and lower the overall cell voltage, minimizing electrical energy loss during operations.
Can the specifications of the stainless steel cathodes be customized?
Yes, specifications including length, width, thickness, lifting lug positions, and surface treatments (such as polishing, sandblasting, or conductive coatings) can be fully customized to match your specific electrolytic cell dimensions and process demands.
What are the environmental benefits of using stainless steel cathodes?
Stainless steel is fully recyclable, which reduces industrial waste. Additionally, the optimized design improves current efficiency and lowers energy consumption, aligning with the principles of green metallurgy.
