Heat treatment at Veldener

We use the following processes to increase the wear-resistance and flexural strength, and thus the resilience and fatigue strength of components.

Select operation:

  • Case hardening
  • Carbonitriding
  • Inductive hardening
  • Short-time gas nitriding (gas nitrocarburizing)
    and long-time gas nitriding
  • Tempering

Case hardening

  • Automatic multi-chamber furnace
  • Integrated pre-heating furnace
  • Integrated cleaning system
  • Carburizing in a gaseous atmosphere
  • Quenching in oil
  • Case hardening depth from 0.3 mm to 2.0 mm

Carbonitriding

  • Automatic multi-chamber furnace
  • Case hardening of low-alloy steels possible
  • Nitrogen as an alloying element
  • Case hardening from 0.1 mm to 1.1 mm

Inductive hardening

  • Systems in medium and high frequency range
  • Horizontal and vertical systems
  • Robot handling
  • Marginalized layer hardening depth from 0.3 mm to 7.00 mm
  • Partial hardening on component possible
  • Seperation and hardening of small batches possible

Short-time gas nitriding (gas nitrocarburizing)
and long-time gas nitriding

  • Nitriding depth from 0.1 mm to 0.6 mm
  • Compund layer thickness from 2 µm to 20 µm
  • Increased corrosion resistance by subsequent oxidizing possible

Tempering

  • Tempering of components to reduce tension
  • Temperature range 140 to 250ºC
