What are the advantages of applying black oxide surface treatment to Rail Clips?

Rail elastic clip is used to fasten the rails to the underlying base plate together with the concrete sleeper. Usually rail clips are made of forged spring steel which is produced by hot forging process. Because of the uniform microstructure of forged clips, it is considered to be better than other metal forming process.

There are several types of railway fasteners. Elastic rail clips are in a category called elastic fasteners. They can be engaged in line with the rail in E-clip fastening, or called fast clip fastening system. Both serve very well in attaching the rail track to the base plate and most importantly controlling those longitudinal forces.

GNEE RAIL supplies E-clips, PR clip, SKL clips, Russia rail clip, Deenik clip, Nabla spring blade, KPO rail calmp, gantrex rail clips, fast clip, crane rail clip and other special clips for rails. We have proffesional production cline to design and manufacture standard rail clips or nonstandard clips. welcome to as.

Applying a black oxide treatment to rail elastic clips offers several advantages, including enhanced corrosion resistance, reduced friction to prevent wear, improved durability, and minimal impact on the clips' critical dimensions. These benefits extend the service life of the clips, especially in harsh conditions, and maintain the high-precision fit required for rail applications.

Advantages of black oxide treatment for rail clips

• Corrosion Resistance: Black oxide forms an oxide layer that significantly improves a part's protection against rust and corrosion, especially when combined with oil or wax post-treatments.

• Reduced Friction and Wear: The coating, often paired with oil, lowers friction between moving parts, which reduces wear and tear and helps prevent galling, ensuring smoother functionality.

• Enhanced Durability: The tough, stable surface created by the black oxide process increases the clip's overall durability and lifespan, making it more resistant to abrasion.

• Dimensional Stability: The coating is extremely thin, adding virtually no thickness to the part. This is crucial for rail clips, which require precise dimensions to function correctly.

• Cost-Effectiveness: Black oxide is generally a more cost-effective surface treatment compared to processes like electroplating or powder coating.

• Aesthetics: It provides a uniform, non-reflective matte black finish, which can be desirable in some applications.

• No Hydrogen Embrittlement: This treatment does not cause hydrogen embrittlement, a potential issue with some other plating and coating processes.
