Technical Specifications
Product Overview
Metallurgical Characteristics
Nickel plated steel features a low-carbon steel substrate with a dense, adherent nickel coating applied through electroplating. The nickel layer provides a barrier against corrosion while maintaining the mechanical properties of the base steel. The coating exhibits excellent ductility and conformability, making it suitable for forming operations after plating.
Coating Process Technology
MetalZenith employs a multi-stage electroplating process beginning with thorough surface preparation including degreasing, pickling, and activation. The nickel plating is performed in controlled sulfamate or Watts nickel baths with precise current density and temperature control to ensure uniform coating thickness and optimal adhesion.
Advanced Manufacturing Process
Our manufacturing process includes automated line handling systems with real-time thickness monitoring and quality control checkpoints. Post-plating treatments include stress relief annealing when required and comprehensive inspection using X-ray fluorescence for thickness verification and visual inspection for coating integrity.
Specialized Quality Testing
MetalZenith conducts comprehensive testing including coating thickness measurement using magnetic and eddy current methods, adhesion testing per ASTM B571, salt spray corrosion testing (ASTM B117), thermal cycling tests, and electrochemical corrosion potential measurements to ensure superior performance in service environments.
Application-Specific Considerations
For chemical equipment applications, we optimize coating thickness and purity to resist specific chemical environments. Food industry applications receive FDA-compliant coatings with enhanced surface smoothness. Medical device components feature ultra-pure nickel coatings with controlled surface roughness. Marine applications utilize thicker coatings with enhanced salt spray resistance, while architectural applications focus on aesthetic finish quality and long-term appearance retention.
