🔧 Application Background | Surface Cleaning Challenges Post Heat Treatment
In steel manufacturing, processes like annealing, normalizing, quenching, and tempering commonly leave behind a tough, coarse oxide scale layer (also known as mill scale or black oxide) on the metal surface. If not properly removed, this layer can negatively impact:
Paint adhesion and surface finish
Plating uniformity
Weld joint integrity
Precision of downstream machining
Traditional methods—such as wire brushing, pickling, and high-pressure water jets—are often effective but come with drawbacks like metal surface damage, environmental hazards, operator safety risks, and high equipment costs.

🧽 YDNFoam™ Solution | The Green, Non-Abrasive Alternative
YDNFoam™ High-Density Melamine Foam uses a 3D microcellular structure with superior flexibility, heat resistance, and chemical stability. It allows for effective wiping of oxide, oil, and residue without damaging the base metal—making it ideal for initial cleaning and surface preparation after heat treatment.
