An E-Rail Clip (or E-Clip) is a high-strength, spring-steel fastener used in railway systems to securely attach rails to sleepers (ties), providing durable alignment and absorbing vibrations from passing trains, ensuring track stability for heavy-haul, high-speed, and freight lines.
What is the manufacturing material of the E type tension clip?
E-type tension clips, especially railway ones, are primarily made from high-strength spring steel, such as grades like 60Si2MnA, 60Si2CrA, 55Si2Mn, and 38Si7, chosen for their exceptional elasticity, fatigue resistance, and durability, though other materials like stainless steel or carbon steel are used for general-purpose E-clips.

Common Materials:
- Spring Steel (Most Common for Railways): Offers superior performance for railway applications where high tension and repeated stress are common.
- Specific Spring Steel Grades: 60Si2MnA, 60Si2CrA, 55Si2Mn, 38Si7.
- Stainless Steel: Used for corrosion resistance in specific environments.
- Carbon Steel: A common base for general-purpose E-clips.
E type clip Types and Specification
E rail clip provide positive and durable rail alignment under the harshest working conditions, which extend the life of railway track. Generally, e rail clips are available at the range from 18mm to 23mm diameter. Rail –e clip is usually made of spring steel. As an important type of elastic rail clips, E-rail clip has a lot of sizes, such as E1, E2, E3, E1609, E1809, E1817, E2001, E2006, E2009, E2055, E2056, etc.
