Sandvik Hiflex® is a hardened and tempered martensitic stainless compressor valve steel alloyed with molybdenum. The material is characterized by:

  • High strength and good 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
  • Good wear resistance

Sandvik Hiflex® compressor valve steel has good dimensional tolerances and good flatness.
