How to prevent rail clips from rusting?
To prevent rail clips from rusting, you can apply a surface coating like hot-dip galvanizing, powder coating, or paint, or use a protective lubricant like corrosion-inhibiting grease. Additionally, ensure clips are properly installed and maintained, keep them clean and dry, and store them in a well-ventilated area to minimize their exposure to moisture.
Surface treatments and coatings
- Hot-dip galvanizing: A common and effective method for industrial use, providing a protective zinc coating.
- Electroplating: Involves an electrochemical process to apply a protective metal coating.
- Phosphating: Creates a conversion coating that improves paint adhesion and corrosion resistance.
- Dacromet coating: Offers enhanced corrosion protection for fasteners and other metal parts.
- Painting: A basic but effective method for creating a barrier. Use rust-resistant or corrosion-inhibiting paints and reapply as needed.
- Powder coating: A durable and protective finish that can be applied to the clips.
Lubricants and greases
- Corrosion-inhibiting grease: Apply specialized grease containing antioxidants, anti-rust agents, and other additives that are more effective than standard grease for railway applications.
- Oiling: A simple method of applying a protective oil film to prevent rust.
Proper installation and maintenance
- Ensure correct installation: Make sure the clips are installed properly to ensure stress is applied evenly across all components.
- Clean regularly: Keep the clips clean to prevent dirt and debris from trapping moisture.
- Maintain tightness: Regularly check that the clips are tight and in good contact with the rail.
- Avoid repeated disassembly: Minimize how often clips are disassembled to avoid damage that can lead to rust.
Storage
- Store in a dry area: Keep spare clips in a clean, dry, and well-ventilated location, away from direct sunlight, oil, and solvents.
Detailed Specification of Various Clips
Rail clip is used to fix the railroad track to underlying baseplate and sleepers. The clamping force by rail clips helps to maintain the gauge and prevent the rail from moving in the vertical and horizontal direction relative to the sleeper. One extensively used type of rail clip is an elastic rail clip made of hot-pressed spring steel. Its energy produced at elastic deformation can alleviate the vibration and shock when trains moving.

Raw Material for Elastic Rail Clip
Elastic rail clips are made of high quality spring steel bar. These steels are generally low-alloy Manganese, medium-carbon steel or high-carbon steel with a very high yield strength. Spring steel has excellent comprehensive performance like mechanical properties, performance by the bullet-proof, fatigue, hardenability, physical and chemical properties.
The raw materials of elastic railroad clip mostly include 55 Si7, 60 Si7, 65 Si7, 55 Si Cr7, 60Si2MnA, 60Si2CrA, 55Si2Mn, and 38Si7 grade of spring steel.
