Enamel Tech Breakthrough: 304 Steel Coils Replace Tungsten Carbide for Cost & Efficiency

Recently, our company, in collaboration with downstream partners, has achieved a major breakthrough in the application of enameled materials. A 4mm diameter 304 stainless steel coil, treated with a special enameling process, has successfully passed textile machine testing and is about to enter mass production. This innovative application not only provides textile companies with a new high-performance, low-cost option, but also marks a key step forward in the advancement of enameled materials in the field of industrial wear resistance.

Previously, textile companies generally used tungsten carbide coils, but the high raw material costs and processing fees have long restricted the industry's ability to reduce costs. Given the wear resistance and glossiness requirements of coil materials for machinery, we found that using 4mm diameter 304 stainless steel enameled coils instead of tungsten carbide coils is more cost-effective.

However, the key technical challenge lies in applying an enamel layer to fine stainless steel. Our R&D team optimized the enamel glaze formula and firing process, successfully forming a dense enamel layer on a 304 stainless steel substrate. This material significantly improves wear resistance and surface hardness compared to traditional tungsten carbide, while maintaining a mirror-like gloss, fully meeting the demands of high-speed textile processing.

The widespread adoption of enameled stainless steel coils has reduced the material cost of a single unit by approximately 10% and extended its service life by 1.2 times that of the original solution. A satisfied customer commented, "The enameled solution retains the wear resistance of tungsten carbide while avoiding the risk of brittle fracture, resulting in significant overall benefits."
