Heat treatment technology

Our worldwide patented HSH® process (Head Special Hardened) is an in-line heat treatment technology for the manufacture of heat treated premium rails. Developed by voestalpine Schienen it is directly integrated into the manufacturing process and offers the following benefits for the customer:

  • High hardening depth (deep head-hardened)
  • Best homogeneity over cross-section and length
  • All sections (vignol, grooved and tongue rails) up to 120 m in length
  • Environmentally-friendly production

The new double heat treatment plant allows the heat treatment of pearlitic and bainitic rails for diverse areas of application according to the highest quality requirements and without capacity limitations for maximal product availability.
