TOHKEN THERMO OVERVIEW
Years of Experience
Around the wold
The tempering is a heat treatment applied to iron alloys, such as steel or cast iron, to achieve a greater hardness of the alloy. The increase in hardness is accompanied by an increase in fragility. Tempering is usually carried out after tempering and is sometimes considered as the same process since a tempered and non-tempered steel is not very usable due to its high brittleness.
Tempering is a treatment to a material in order to decrease the tension of the tempered material. The fundamental purpose is to reduce the great fragility that steels have after tempering.
Controlling temperature, time and pressure in pieces of thin wall to rectify the deformation caused by the temper and to diminish the fragility.
Thermochemical treatment in which carbon is added to the surface of a piece with low carbon content by diffusing a carbon-rich gas without affecting the core of the piece.
Surface hardening treatment, thin film formation by diffusion of nitrogen and carbon on the surface.
Treatment applied to steel parts with low carbon content generating a surface layer formed by carbides and nitrides to obtain a high resistance to wear.
HEAT TREATMENT SERVICES
The types of general treatment: tempering and tempering, vacuum, aluminum solution, stainless steel, normalized, annealed among others. Surface treatment: carburization, carbonitriding, gas nitriding, soft nitriding with gas, gas nitriding by sulfurization, quenching and tempering by induction; Thin Film Formation Treatment: physical vapor disposal, vanadium carbide.
