What is the material of elastic rail clip?

Jan 28, 2026

A rail clip is a spring steel fastener that fixes rails onto sleepers or baseplates by elastic restraint, enabling vibration damping while ensuring precise rail positioning and consistent gauge under continuous traffic loading.

What is the material of elastic rail clip?

 

Elastic rail clips are manufactured from high-grade, hot-forged spring steel (such as 60Si2MnA, 55Si7, or 60Si2CrA) designed for high fatigue resistance and strength. These fasteners are used to secure rails to concrete or wooden sleepers, providing essential clamping force (around 2 tons) while resisting vibration and maintaining track gauge.

 

Key Details About Elastic Rail Clip Material:

 

  • Material Types: Primarily 60Si2MnA, 55SiCr7, 55Si7, 60Si2CrA, and 38Si7 spring steel.

What are railroad clips used for?

 

Railroad clips (or elastic rail clips) are crucial fastening components used to secure steel rails to ties (sleepers) and baseplates, maintaining gauge integrity and preventing longitudinal movement caused by temperature changes and vibration. They absorb impact energy, reduce track maintenance needs, and are essential for heavy-haul or high-speed rail lines.

 

Key Purposes and Functions:

 

rail fasteners

 

  • Secure Fastening: They hold the rail down with significant force (approx. 2 tons per clip), preventing vertical and horizontal movement.

 

  • Safety and Stability: By keeping the rails firmly attached to the sleepers, they prevent warping and buckling.

 

  • Impact Absorption: Made from forged spring steel, these clips act as a cushion, absorbing vibrations and shocks from passing trains.

 

  • Maintenance Reduction: Known as "fit and forget" components, they require minimal maintenance compared to traditional spikes.

 

What are the features of ERC Rail Clip?

 

Rail clips are specialized fasteners, such as E-type, SKL, and Nabla clips, designed to secure steel rails to sleepers, providing high clamping force, excellent elasticity, shock absorption, and long-lasting fatigue resistance. Key features include maintaining accurate track gauge, reducing noise, and enabling quick installation for modern, high-speed, or heavy-haul railways.

 

Key Features of Rail Clips

 

  • High Elasticity & Clamping Force: Ensures the rail remains securely fastened to the baseplate/sleeper, preventing vertical or lateral movement.

 

  • Vibration Reduction: Effectively absorbs dynamic shocks and noise, reducing damage to components and improving safety.

 

  • Fatigue Resistance: Engineered to withstand repeated, high-intensity loads (e.g., millions of cycles) without breaking.

 

  • Easy Installation/Removal: Designed for quick installation or removal using specialized tools, reducing maintenance time.

 

  • Corrosion Resistance: Often treated with surface coatings (plain, oil, black oxide) to survive harsh environmental conditions.

 

  • Electrical Insulation: When used with plastic components, they provide necessary electrical isolation for track circuits.
