Heat treatment

Salt bath annealing:

  • Salt bath annealing for steel materials with annealing temperatures of up to 980 °C
  • Quenching in a hot bath at 220 °C
  • Maximum annealing length: 3000mm
  • Furnace diameter 400mm


  • Max. furnace dimensions: 900mm x 900mm x 4000mm

Induction hardening:

  • Induction hardening technology in the mid-frequency range for the hardening of work pieces of up to 4000mm in length
  • The processed hardening length and edge-hardening depth will depend on the material and geometric shape
  • Inductors manufactured in our own in-house facility
  • Other heat treatments such as vacuum hardening, nitrating and insertion are offered in cooperation with reliable partners


  • Demagnetising of work pieces offered as service on a high-performance demagnetising system
  • We can demagnetise components made of ferromagnetic materials with a cross-section of 200 x 180mm, max. length of 3000mm und max. weight of 500kg
  • We can achieve residual magnetism values of less than 2 A/cm, depending on how the magnetism was introduced into the work piece. This represents a common value in the ball bearing industry


  • Spectral analysis of iron-based metals
  • Microstructure examination
  • 3D measuring machines with traverse range of 650mm x 500mm x 4000mm
