Heat treatment

Component & knife hardening

As a developer and knife manufacturer, we are also in a position to respond to our customers needs and requirements in terms of heat treatments. From a wide range of proven processes, we can select the ideal process for the particular knife and its planned application in-house. The most important processes and technologies for heat treatment of knives & blades are:

Heat treatment bainitizing

Bainitizing is especially suitable as heat treatment, for components with a high carbon content. The metal will be heated to the required hardening temperature and then, for a certain time, held in a tempered quenching medium. We use a salt solution for this purpose. The process creates a so-called bainitic structure that hardens the steel.

  • Lower risk of fracture with high hardness
  • Less distortion with thin components

Martensitic hardening

With this process, multi-purpose chamber furnaces or continuous furnaces are being used. The steel components and knives are heated to the required hardening temperature and quenched with oil. This is followed by another tempering process to reduce stresses in the material and to achieve the desired hardness.

  • Very high hardness and strength
  • High wear resistance
  • High temperature resistance

Zone hardening of knives & cutting edges

With this process, predefined areas of a component can be partially hardened using induction coils. The tempered components are then quenched in a water solution and subjected to a tempering process, to reduce stresses in the material.

  • High hardness in defined component areas
  • High strength in defined component areas
  • High wear resistance in defined areas of the component

Combined heat treatment

The possibility of combining different heat treatment technologies is exploited. For example, knives can be produced with a bainitized base hardness and a zone-hardened cutting edge. This way we combine the advantages of both processes: Premium knives with high toughness in the component part and a high wear resistances on the cutting edges are being used in our customers harvesting machines.
