Flame Hardening |
During the flame hardening
process the surface of the work piece will be heated up to
the austenitization temperature. This is realized with the
flame of an acetylene burner. After the respective temperature
and the predetermined depth are reached the work piece will
be quenched with a matching quenching agent. This process
hardens only the surface and leaves the core unaffected. This
way the surface becomes wear-resistant and the core keeps
the characteristics generated with eventual previous heat
treatments. Several millimetres of hardening depths can be
reached with the induction hardening process.
