Heat treatment

Heat treatment

Essential complement of the forge. The product has to undergo a heat treatment after forging operation to retrieve the mechanical characteristics modified during the heat.

Performed in 2 or 3 stages, among which:

  • Quenching (with oil)
  • Tempering
  • Normalisation
  • Structural refining
  • Annealing
  • Stress relief
  • Ageing

This controlled atmosphere treatment is the result of an informed mix of expertise and valuable feedback data.

We control the mechanical characteristics of our products. You have a special need for your fasteners? We have the know-how to modify the mechanical characteristics of the fastener, according to the capacities of the grade concerned.

A supervisory system provides all the traceability elements required by industry-leading standards.
