HARTMIL

HARTMIL

HARTMIL hardening oils are formulated upon deeply refined mineral oils, adequately enhanced with improvers, speeding the cooling processes and inhibiting sealing-wax and deposits formation on the surfaces of the hardened elements.

1ton

Application

The oils are designed for:

  • thermal treatment of cast iron and steel elements, in particular in closed hardening furnaces with controlled atmosphere, which require high purity of the hardened surfaces.
  • thermal treatment of cast iron and steel elements, which are allowed for small geometrical deformations with the appropriate cooling speed required.

Guarantee

  • effective thermal treatment of cast iron and steel elements,
  • high purity of the hardened surfaces.
