Chemical element making brittle the steel by its tendency to thicken the grain and decrease the plasticity of the ferrite. In small percentages (<0.10%) it can cause an increase in hardness and tensile strength to the detriment of toughness. For this reason it is an element that must be minimized in steel; different standards limit…
DetailsRemoval of surface oxide from steel after hot rolling. Steel at high temperatures reacts with the environment, producing a phenomenon of surface oxidation that results in the generation of ferrous oxide and ferric oxide on the surface of the pieces, generating a hard, fragile and abrasive layer that can produce damages in subsequent processes in…
DetailsMaterial that has been subjected to the quenching treatment: heating until complete austenization of the steel piece, followed by a subsequent severe cooling that gives rise to a structure (martensitic), which provides it with the greatest hardness and mechanical resistance that can be obtained in steels . The piece only quenched hardly has application because…
DetailsHeat treatment also called tempered, which consists of the treatment preparing the quenching, followed by the treatment conditioning the tempering. The result is resistant and tough pieces.
DetailsThey are alloyed carbon steels with elements so that they have greater hardenability. In thick pieces, carbon steels cannot be tempered in all their thickness; this type of steels, thanks to the alloy, improve the penetration of quenching, obtaining extraordinary mechanical characteristics with respect to carbon steels. They are characterized by a good toughness for…
