The 60Si2Mn is a high-performance elastic fastening component widely used in railway track systems, especially for heavy-load and high-frequency lines. Manufactured from premium spring steel 60Si2Mn and treated through precise heat and tempering processes, it offers exceptional strength, fatigue resistance, and elasticity to withstand dynamic impact and vibration from train operation.
Surface treatment options-such as oxide black, hot dip galvanizing, or Dacromet coating-are available depending on environmental conditions. The oxide black finish enhances rust and wear resistance, while hot dip galvanizing is ideal for humid or coastal regions, significantly extending the clamp's service life.
The Deenik clip features a compact structure that maintains stable clamping force while allowing controlled elastic deformation. This ensures track gauge stability and reduces sleeper stress during high-speed train operation. Its unique geometric design and optimized clamping angle provide secure rail retention, preventing track displacement and loosening.
