Laser hardening - Technical Data

tube, surface hardened (cross-section)
  • Crack-free
  • Little or no deformation
  • Maximum track widths up to 30mm
  • Minimum track widths approx. 1mm
  • Planar hardening possible
  • Hardening depths of 0.1..2.0mm
  • Oxidation-free if desired


As a general principle, any iron and steel materials with a carbon content of more than 0.3% can be hardened. The more fine-grained the structure, the better the hardenability with the laser (pre-hardened steels).

Examples of frequently used materials which can be laser-hardened are 42CrMo4, Ck60, C45, 51CrMoV9, Vanadis 6, 1.2344, 1.2379, lamellar grey cast iron and spheroidal graphite cast-iron.
