STEEL HEAT TREATMENTS
Quenching and tempering: Quenching and tempering is the entire heat treatment cycle of austenitization.
Normalizing: Full austenitization heat treatment followed by cooling in air until room temperature.
Annealing: Annealing is the heat treatment of austenitization followed by slow cooling in the furnace to obtain the transformation of the austenite under conditions closer to equilibrium.
Distension/ Stabilization: heating to a temperature between 150 and 250°C to eliminate the structural tensions of tetragonal martensite obtained by quenching.
Subzero treatment: Under-cooling treatment carried out after carburizing, before tempering, with the task of transforming a possible excess of residual austenite of the cemented layer.
THERMOCHEMICAL TREATMENTS
Our thermochemical treatments on steel are carried out in appropriate atmospheres generated by the use of “technical gases”.
The SOLO Swiss plant, thanks to their useful dimensions, allow the vertical hardening of parts up to 1050 mm in height. In addition, multi-sector electric heating, together with the type of distribution of the charge, allows an excellent temperature uniformity within the chamber allowing better control over deformations.
The task of the carburizing is to harden the surface layer of the material to make it resistant to wear, but in some cases it is necessary to exclude some areas that if carburized would be excessively fragile such as threads.
To do this, a special paste is applied manually in the areas to be protected.
Shot blasting is a process of propulsion of abrasive material (microspheres and/or cylinders) against the surface of the pieces, and is intended to smooth a rough surface, enrich a smooth surface, or remove contaminants such as oxides or residues from treatments such as quenching in oil.
The shot is made with different machines in relation to the shape, size and material of the particular.
The carburizing treatments also lead to the stabilization of the austenite, which, as a result of tempering, often fails to transform completely into martensite, thus generating residual austenite.
The residual austenite is unstable at room temperature, therefore its presence could compromise the mechanical characteristics of the material, for this reason, a sub-zero treatment is carried out which has the task of transforming the metastable austenite into martensite.
Our laboratory has some of the most advanced materials analysis technologies. We are able to carry out hardness tests and micrographic analyses on different types of material, depth analysis of carburizing, residual ß phase analysis on brass and fracture analysis.
At the request of the customer we provide pick-up and delivery services throughout the north and central Italy.
Thanks to our transportation we are able to carry out transport with a maximum capacity of 30 tons, and we work with specialized transporters for every type of exceptional transport.
