Product Introduction
SKL fastener system is an important device to ensure the fixation of rails in railway track engineering. It is composed of multiple functional components. It realizes the reliable connection between rails and sleepers through mechanical fastening, effectively suppresses the displacement of rails, and ensures the stability of track geometry. The system uses high-quality spring steel 60Si2MnA and high-performance engineering plastics. After strict production process and quality inspection, it has good comprehensive mechanical properties and environmental adaptability.
60Si2MnA SKL Clamp Rail Fastening is a commonly used fastener system in railway track construction. After appropriate heat treatment, the tensile strength of 60Si2MnA steel is ≥1570MPa, which can withstand the huge pressure and impact force generated by long-term train operation and is not prone to fatigue damage, ensuring that the fastener system maintains stable performance in long-term use and reduces the frequency of maintenance and replacement.
