As a professional manufacturer with over 25 years of experience in the railway fastener industry, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Heat Treated E-type Elastic Rail Clip with a hardness of 70-80 HRC, specifically designed for heavy load applications. Our factory, established in 1998, has been exporting high-quality rail fastening components to markets across North America, South America, Europe, Southeast Asia, Africa, and Oceania, with an annual export value exceeding US$5 million. This clip is engineered to deliver exceptional clamping force and fatigue resistance, ensuring secure rail fixation even under extreme loading conditions.
The E-type elastic rail clip undergoes a precise heat treatment process that achieves a uniform hardness of 70-80 HRC, providing superior wear resistance and long service life. It is crafted from premium spring steel, offering excellent elasticity and resilience. Below are the key product features and technical specifications:
- High Hardness (70-80 HRC): Optimized for heavy-duty tracks, reducing deformation and maintaining consistent clamping force over time.
- Heat Treated for Durability: Advanced heat treatment enhances fatigue strength and prevents brittle fracture.
- E-type Design: Proven geometry for reliable rail fastening, compatible with standard rail clips and insulators.
- Customizable Dimensions: Available in various sizes to match UIC, AREMA, and other international standards, or tailored to your specific requirements.
- Corrosion Protection Options: Surface treatments such as black oxide, hot-dip galvanizing, or oiling can be applied upon request.
- Consistent Quality: Each batch is tested for hardness, tensile strength, and dimensional accuracy to ensure conformity.
