Chrome silicon spring wire
Chrome silicon spring wire

Chrome silicon can withstand higher and lower temperatures than high-carbon steels and particularly for working conditions including high stress and applications where shock or impact loading occurs. This metal is often used as large-diameter spring wire which can handle higher stress than chrome vanadium. Chrome silicon wire spring are available in size ranges from 0.0217” to 0.312”.


  • Suitable for considerable shock and extreme high temperatures.
  • Higher stresses than Chrome Vanadium;
  • Finest surface in automotive industry.
