What materials are used to make the E2006 elastic rail clip?
The E2006 rail clip from GNEE RAIL is primarily manufactured using 60Si2Mn spring steel, with additional high-performance steel grades including 60Si2MnA, 60Si2CrA, 55Si2Mn, and 38Si7 available to meet specific project requirements. These spring steel grades are selected for their excellent elasticity, fatigue resistance, and structural stability, which enable the E2006 rail clip to maintain consistent clamping force under heavy load and harsh operating conditions. As a core component of the E-type rail clip fastening system, the E2006 rail clip delivers reliable rail alignment and long service life for various railway applications.
Material Grades and Chemical Composition
The steel grades used for the E2006 rail clip are carefully formulated to balance strength, toughness, and elastic performance. 60Si2Mn, the standard material for the E2006 rail clip specification, contains 0.52-0.60% carbon, 0.60-0.90% manganese, 1.50-2.00% silicon, with chromium content limited to ≤0.35%, phosphorus ≤0.03%, and sulfur ≤0.03%. For projects requiring higher strength or enhanced corrosion resistance, 60Si2MnA and 60Si2CrA e2006 rail clip variants are available.
60Si2MnA features a carbon range of 0.56-0.64%, manganese 0.60-0.90%, and silicon 1.60-2.00%, while 60Si2CrA adds 0.70-1.00% chromium to improve hardenability and wear resistance.
Additional steel grades such as 55Si2Mn and 38Si7 are also part of the available material portfolio, allowing buyers to select the optimal grade based on their load, climate, and maintenance needs. All these steel grades comply with recognized industry standards including DIN17221, BS970, and GB/T1222, ensuring consistent material quality across production batches.

| 60Si2MnA | 0.56-0.64 | 0.60-0.90 | 1.60-2.00 | ≤0.35 | ≤0.03 | ≤0.03 |
| 60Si2CrA | 0.56-0.64 | 0.40-0.70 | 1.40-1.80 | 0.70-1.00 | ≤0.03 | ≤0.03 |
| 55Si2Mn | 0.52-0.60 | 0.60-0.90 | 1.50-2.00 | ≤0.35 | ≤0.03 | ≤0.03 |
| 38Si7 | 0.35-0.42 | 0.50-0.80 | 1.50-1.80 | - | ≤0.03 | ≤0.03 |
GNEE RAIL implements strict quality control throughout the supply process, including chemical composition analysis and mechanical property testing for every batch of E2006 rail clip materials. Mill Test Certificates (EN 10204 Type 3.1) are provided with every shipment to verify material traceability and compliance with specified steel grades.
Mechanical Performance of E2006 Rail Clip Materials
The spring steel materials used for the E2006 rail clip deliver exceptional mechanical properties that support long-term reliable performance in railway track systems. The finished E2006 rail clip has a hardness range of 44-48HRC, which provides the ideal balance between rigidity and elastic deformation capacity. This hardness level ensures the clip can withstand repeated loading from passing trains without permanent deformation or loss of clamping force. For fatigue life, the E2006 rail clip, with its 20mm nominal bar diameter, achieves no less than 5 million cycles without breaking, making it suitable for high-traffic mainline routes, heavy haul lines, and high-speed rail applications. The toe load for the 20mm diameter E2006 rail clip falls within the 1100-1400kgf range, providing secure rail holding while allowing controlled rail movement during thermal expansion and contraction.

These material properties directly contribute to the key benefits of the E2006 rail clip, including vibration absorption, consistent gauge holding, and reduced track maintenance requirements. The elastic clamping action of the 60Si2MnA spring steel clip reduces stress on rail sections, extending the overall service life of the track structure. The E2006 rail clip is compatible with concrete, wood, and steel sleepers, and works as part of a complete E-clip fastening system that includes shoulders, rail pads, and insulators for full track assembly.

Surface Treatment Options for E2006 Rail Clip
To protect the spring steel base material from corrosion and wear, the E2006 rail clip is available with multiple surface treatment options. Standard finishes include plain oiled, which provides basic rust prevention during storage and transit, and black oxide for improved corrosion resistance in moderate environments. For projects in high-humidity, coastal, or chemically aggressive environments, hot-dip galvanized (HDG) and zinc electroplating finishes are available to extend the service life of the clip.

Additional surface treatments such as color painting, wax coating, bituminizing, and Dacromet coating can also be provided according to customer requirements. Each surface treatment is applied under controlled process conditions to ensure uniform coverage and strong adhesion to the steel substrate, without compromising the elastic or mechanical properties of the E2006 rail clip.
