54A031 - Walter SURFOX-M Black Marking Electrolyte, 100ml

Advanced Electrochemical Marking Electrolyte for Stainless Steel

The Walter SURFOX-M Stainless Steel Marking Electrolyte (54A031) is a sophisticated chemical formulation developed to facilitate the permanent marking of stainless steel surfaces through electrochemical oxidation. This process, often referred to as electrochemical etching or marking, utilizes Alternating Current (AC) to induce a reaction between the electrolyte and the metal substrate. The result is a high-contrast, durable black mark that becomes an integral part of the surface rather than a superficial layer. This method is distinct from mechanical engraving, which can create stress risers, and laser marking, which requires significant capital investment. SURFOX-M allows fabricators to leverage their existing SURFOX weld cleaning systems to perform high-quality marking operations efficiently.

Engineered for precision and consistency, SURFOX-M is the ideal solution for applying intricate designs, including company logos, barcodes, QR codes, and alphanumeric text. When used in conjunction with a PRO or Standard marking kit, the electrolyte ensures that current is distributed evenly across the stencil area, resulting in sharp edges and uniform darkness. This capability is essential for compliance with industry standards requiring permanent part identification and traceability, particularly in sectors such as medical device manufacturing, food processing equipment, and architectural fabrication. The solution is compatible with various grades of stainless steel, including the commonly used 300 series (e.g., 304, 316), ensuring versatility across different projects.

Durability is a key characteristic of the markings produced by SURFOX-M. Because the process modifies the surface oxide layer, the resulting black mark exhibits exceptional resistance to mechanical abrasion, chemical cleaning agents, and environmental factors. It will not peel, chip, or fade over time, maintaining legibility under rigorous service conditions. The 100ml bottle is designed for ease of application and storage, providing a sufficient quantity of electrolyte for hundreds of individual markings depending on size. Users must ensure the machine is set to AC mode, as Direct Current (DC) is typically reserved for cleaning and electropolishing functions. Following the marking process, it is critical to neutralize the surface to remove any residual electrolyte, thereby preserving the passivation of the stainless steel and preventing future corrosion.

In summary, Walter SURFOX-M transforms standard weld cleaning equipment into a powerful marking station. It offers a chemical solution that balances reactivity with control, allowing for the rapid application of permanent data without compromising the surface integrity of the stainless steel. This product represents a convergence of chemical engineering and electrical surface treatment, providing a reliable, industrial-grade method for metal identification.
