BeariNg steeLs

Typical Cr steels with 1% average C content fall within this category. Their main characteristics are high hardness, wear resistance and compression resistance, the latter two enhanced by the high level of micro purity obtained by special elaboration procedures. For this reason, they are universally used for the manufacture of roller bearings spheres, coils and rings.

Stainless steel is the name for iron, chrome and carbon alloys, which sometimes include other elements such as Ni – Mo – Si – etc., whose main characteristic is corrosion resist- ance. This characteristic is ascribable to their ability to passivate in an oxidizing environ- ment (for example air). Passivation is the formation of an invisible layer of oxide, which varies according to the chemical composition of steel. The indispensable condition for the formation of the protective layer is a chromium rate of at least 11%.

Hand tools steel is steel that is going to be part of equipment subject to stress. The main characteristics required from this kind of steel are: high cutting capacity, high wear re- sistance, resistance to repeated impacts, high hardness after hot and/or cold treatment, dimensional stability after heat treatment.

These types of structural steels are meant for quenching and tempering treatment (quenching followed by tempering at around 600°C). Generally speaking, quenched and tempered steels are used for the manufacturing of mechanical components subject to static and dynamic loads; they find wide application in mechanical industries for all types of shafts, axle-shafts rods, connecting rods, connecting components, levers, rods for power hammers, pillars, presses etc.; all the steels that fall into this category can be supplied quenched and tempered with reference to specific characteristics.

case-HarDeNiNg steeLs

They include structural steels with < 0.25% carbon meant for surface hardening treatment, consisting in the carbon enrichment and subsequent quenching of the part’s surface, granting high surface hardness with excellent wear resistance, while the low carbon content of the core allows for high resistance values in the underlying mass. Case- hardening steels are used for the manufacture of mechanical parts such as: all types of gears, axes, cones, pins, bushes, nuts, distribution and transmission shafts etc.

tOOL steeLs

Cold work tool steels:
It includes tool steels meant for the construction of equipment where conditions of use are such that working temperatures are kept below 200°C.

Hot work steels:
It includes tool steels meant for the construction of equipment where working conditions are such that it is likely that the tool will work, albeit not continuously, at temperatures between 450°C and 600°C.

High speed steels:
It includes steels meant for particularly heavy duties at low temperatures, as well as tasks where high temperatures may be reached locally, such as cutting and cold-working tools.
