What grade steel is used for E rail elastic clip?

E Type Rail Elastic Clip is one of the common track fasteners in the railway fastening system, which is used to provide positive and durable track alignment under harshest working conditions, thus extending the life of railway track. Generally, rail elastic clip is made of forged spring steel with a diameter range from 18mm to 23mm, the main function of rail clip is to fasten railroad sleeper and steel rail together. The rail clip is considered as one of the best ways to ensure that rails not move, bend, warp, etc.

What grade steel is used for E rail elastic clip?

E-rail elastic clips are made from high-quality spring steel, typically specific grades like 60Si2MnA, 60Si2CrA, 55Si7, or 65Si7, chosen for their excellent elasticity, fatigue resistance, and mechanical properties, ensuring they can withstand repeated stress in railway applications. These materials are often silicon-manganese (Si-Mn) alloyed spring steels, heat-treated to achieve a hardness of around 44-48 HRC (Rockwell Hardness) for optimal performance.

Common Steel Grades Used:

60Si2MnA (60Si2Mn): A very common silicon-manganese spring steel.

60Si2CrA: Another high-strength silicon-chromium spring steel.

55Si7 / 60Si7 / 65Si7: Silicon spring steels.

38Si7: A silicon spring steel.

What are the advantages of e-rail clip?

E-rail clips offer advantages like high strength, self-tensioning, and durability, providing safe, reliable rail fastening that reduces vibration, noise, and maintenance by eliminating the need for frequent torque checks, while maintaining precise track alignment for heavy freight and passenger trains.

Key Advantages

• Safety & Reliability: High-strength spring steel construction and secure fastening prevent rail movement, reducing derailment risks and ensuring stable track alignment.

• Vibration Damping & Noise Reduction: Absorb shocks and vibrations from passing trains, improving passenger comfort and reducing track degradation.

• Low Maintenance: Self-tensioning design means they stay tight without regular manual adjustments, leading to lower maintenance costs and more efficient operations.

• Durability: Excellent resistance to corrosion, fatigue, and environmental stress, ensuring a long service life.
