Heat treatment

Processes

Heating through processes

  • Hardening of tool steel
  • Vacuum hardening
  • Quenching
  • Annealing (with / without inert gas)
  • Tempering
  • Deep freezing (up to -60°C)

Thermo-chemical diffusion processes

  • Carburizing
  • Case-hardening
  • Gas nitrogen hardening
  • Gas nitrocarburizing

Dimensions of oven: 680 mm diameter x 1400 mm

Core competences

  • Low deformation hardening with hardening press
  • Mechanical straightening of corrugations up to 5 m, tolerance less than 0.1 mm
  • Vacuum treatment

Nitrogen Hardening

Processes

  • Gas nitrogen hardening
    - All classical processes for tempering and heat-treatable steel
  • Nitrocarburizing
    - Alternative treatment in gas for tenifer treatment, soft nitration
    - All ferrous based materials, from unalloyed to high-alloy steels

Maximum dimensions: 2200 mm long x 900 mm diameter

Special treatments

  • Ledeburitic stainless steels (13-17% Cr)
  • Titanium alloys

Mechanical Straightening

Catalog of services

  • Straightening of corrugations and tubes between turning centres
  • Maximum diameter 150 mm up to 3300 mm maximum length on rolls up to 5000 mm
  • Tolerance depending on dimensions, 0.1 mm or less
