Freeflex™ is a hardened and tempered martensitic stainless compressor valve steel alloyed with copper. The material is characterized by:

  • Excellent combination of high strength and high ductility
  • Extremely high fatigue strength under bending and impact stress
  • Excellent surface finish
  • Very high compressive residual surface stress
  • Low level of non-metallic inclusions
  • Very good wear resistance

Freeflex™ compressor valve steel has excellent dimensional tolerances and flatness.
