Stainless Steel Cathode Plate

Stainless steel cathode plates are highly resistant to corrosion. This durability comes from their high chromium content, which reacts with oxygen to form a thin, invisible, self-healing layer of chromium oxide on the surface.

Known for its mechanical strength, stainless steel can endure heavy loads, thermal cycling, and physical impacts without warping or cracking. Cathode plates made from this material are robust and long-lasting under demanding conditions.

The smooth, non-porous surface of stainless steel resists scale, deposits, and biological contaminants. This makes cleaning simple and reduces the need for frequent maintenance.

Stainless steel provides moderate electrical conductivity while maintaining excellent corrosion resistance and mechanical strength, making it a durable alternative to metals that are more conductive but less stable.

Although the initial cost of stainless steel cathode plates may be higher than some alternatives, their long service life and low maintenance requirements make them a highly cost-effective and sustainable choice over time.

Stainless steel cathode plates are employed in a broad spectrum of industries due to their adaptable performance profile. This versatility stems from the material’s ability to perform reliably under varying pH levels, temperatures, and current densities.

Material Selection and Extrusion

The production process begins with selecting solid copper bars that meet strict technical specifications. These bars are combined with 316L stainless steel pipes through a precision extrusion process. During extrusion, the diameters are carefully reduced to ensure optimal bonding and electrical conductivity in the final conductive rod.

Quality Control and Testing

Comprehensive quality assurance is performed, including third-party resistance testing using advanced digital resistance multimeters. All measurements are calibrated according to stringent international standards.

Surface Manufacturing Process

The cathode plate surface is fabricated from 316L stainless steel plates, processed to meet precise technical requirements. This includes accurately punching lifting holes and milling “V”-shaped grooves in accordance with detailed design specifications.

Laser Welding Process

The final assembly uses a fluxless laser welding process to join the stainless steel cathode plate and conductive bar. The concentrated heat application prevents surface deformation while ensuring stable weld quality. This method guarantees excellent conductivity, mechanical strength, and maintains precise verticality and flatness in the finished assembly.
