Permanent Stainless Steel Cathodes - High-Quality China Suppliers & Factory for Electrolytic Applications
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 (tolerance ≤ ±2mm/m²), ensuring uniform metal deposition and avoiding short circuits or local over-thickness.
- Optimized edge sealing: Edges are designed with flanging or sealing to prevent deposited metal from wrapping around edges, facilitating stripping.
- Robust lifting lug structure: Lifting lugs are firmly welded to the plate body with a reasonable design, facilitating hoisting by crane and stripping operations.
- Lightweight design: Thickness is optimized under the guarantee of strength to reduce weight, lowering material and transportation costs.

Frequently Asked Questions
-
Q What grades of stainless steel are used for permanent cathode plates? ▾Permanent stainless steel cathode plates are typically manufactured from high-quality stainless steel grades such as 304, 316, and 316L. Grade 316 and 316L are especially preferred in highly corrosive electrolyte environments containing sulfuric acid or chloride ions due to their superior corrosion resistance.
-
Q How many times can a stainless steel cathode plate be reused? ▾Stainless steel cathode plates are designed for long-term durability. Under normal operating conditions, they can be reused thousands of times. Their corrosion-resistant and wear-resistant properties significantly reduce replacement frequency and overall maintenance costs.
-
Q Can the cathode plate dimensions be customized for different electrolytic cells? ▾Yes. The length, width, thickness, and lifting lug positions of the cathode plates can all be customized to match specific electrolytic cell sizes, current density requirements, and process conditions. Surface treatments such as polishing, sandblasting, or conductive coating are also available upon request.
-
Q What metals can be refined using stainless steel cathode plates? ▾Stainless steel cathode plates are widely used in the electrolytic extraction and refining of non-ferrous metals, including copper, zinc, nickel, cobalt, and manganese. They are a key component in modern hydrometallurgical processes.
-
Q How does the flatness of the cathode plate affect production quality? ▾The flatness of the cathode plate is critical to production quality. A tolerance of ≤ ±2mm/m² ensures uniform metal deposition across the plate surface, preventing issues such as short circuits, local over-thickness, or uneven metal crystallization. High flatness also makes stripping easier and more efficient.
-
Q Are stainless steel cathode plates environmentally friendly? ▾Yes. Stainless steel is a fully recyclable material, which means end-of-life cathode plates generate minimal waste. Additionally, their high electrical conductivity reduces cell voltage and energy consumption during electrolysis, contributing to a lower carbon footprint and more sustainable metallurgical operations.
