They are steels for the rings and rolling bodies that use balls and rollers to maintain the separation between the moving parts of the bearing. The following types of bearing steels are differentiated (alloyed with one or more of the following elements): hardened throughout their mass (Cr, Mo); hardened by case-hardening (Cr, Mo, Ni), hardened…
DetailsSemi-finished product normally of square section and of dimensions not exceeding 155×155 mm. Its destination is to be hot rolled to get coils or rolled bars. The billet is usually as-cast obtained by continuous casting, although sometimes it can be processed products of casting by means of rolling, forging or cutting to length.
DetailsFurnace used to obtain pig iron by removing oxygen from the iron ore (reduction of iron oxides with carbon from the gases produced by the heat generated by the melting of Coke) and combining the already pure iron with the carbon of the Coke.
DetailsChemical element that increases the hardenability with very small percentages of addition (between 0.0008 and 0.005%) in boron steels. Its effectiveness to increase the hardenability is much greater than that of other quenchant elements like Molybdenum and the Chromium. Visit our boron steels
DetailsThey are steels with a Boron content between 0.0008-0.005%. The precipitation of boron in the austenite grain joints delays the appearance of ferrite and favors the appearance of bainite or martensite in tempering treatments. The boron steels have a good suitability for cold deformation and enough hardenability to ensure the mechanical characteristics required after quenching…
DetailsIt establishes the hardness of a material by means of the indentation method that allows to measure the penetration of an object in the material to be studied. In the test, the indenter is a steel ball of 10 to 12 mm of diameter that rests on the test specimen, exerting on it a force…
