    press-hardened part
    Focus on press hardening and its advantages
    Press-hardening serves a very specific purpose: to prevent part deformation during the rapid cooling phase induced by quenching. This method improves the performance of steels by giving them a martensitic structure, without the need for reworking. Designed for large production runs of parts with complex geometries, [...]

    martensitic-hardened metal parts
    Focus on martensitic hardening and its advantages
    The aim of martensitic hardening is to bring out a specific constituent in steels, called martensite, to make them harder and more resistant to wear and mechanical stress. It is one of the oldest known heat treatments of metals, and is still used today, thanks to its effectiveness and the [...].

    Steel bars of various sizes, illustrating annealing and tempering processes
    Annealing and tempering: what are the differences and what are the different types of annealing?
    Annealing and tempering are among the heat treatment techniques applied mainly to steels (copper alloys, aluminum and titanium too). Both methods involve heating parts to precise temperatures, which vary according to the process, but do not serve the same purpose. There are two main types of annealing [...].

    stepped quenching diagram
    A closer look at step quenching and its advantages
    Staged quenching is based on cooling in stages. It includes a traditional initial heating phase, to reach a given temperature, but requires controlled cooling to be divided into several stages. This process offers a number of advantages, including a reduced risk of breakage or deformation, compared to quenching with [...].

    Bonded varnish Complementary treatment to heat treatment
    Why choose glide varnish as a complementary treatment?
    Bonded coatings are an excellent way of improving the coefficient of friction of metal parts. Applied, possibly following a heat treatment operation, it ensures that the parts slide better together and reduces the risk of seizing. This technology is used particularly in the construction and screw industries, but also in the [...]
