Dati tecnici dell’acciaio

E’ un acciaio legato al nichel-cromo-molibdeno definito autotemprante, cioè assume una struttura di tempra (martensitica) per semplice raffreddamento all’aria, resistente e resiliente a fatica e torsione. Resiliente in ambiente criogenico. Viene utilizzato per la costruzione di particolari estremamente sollecitati, quali alberi, aste, bielle, steli per magli, colonne presse.

Normalmente fornito allo stato ricotto globulare.

Grade technical data

It is a nickel-chromium-molybdenum alloyed steel defined as self-hardening, i.e. it assumes a tempered structure (martensitic) by simply being cooled in air; it is both resistant and resilient to fatigue and torsion. Resilient in a cryogenic environment. It is used for the construction of extremely stressed parts, such as shafts, connecting rods, stems for hammers, press columns.

Normally supplied in the annealed globular state.
