Lucchini 2343 is the pioneer Chromium-Molybdenum- Vanadium alloyed steel designed for the manufacturing
of dies, moulds, punches and other components subjected to high working temperatures. Lucchini 2343 is
one of the most used and appreciated steels for the production of dies and moulds subjected to high working
temperature. Lucchini 2343 is obtained through a special 'super clean' manufacturing process, which allows a
high level of micro-purity.
LUCCHINI 2343 represents one of the most important tough options, for highly resistant plastic moulds that
need very high pressure strength, excellent resistance to abrasion, also in combination with different surface
coatings, and improved toughness in the meantime.
If subjected to suitable hardening, followed by at least two suitable tempers, LUCCHINI 2343 can reach a
hardness of 50 HRC without affecting the toughness.
In order to improve further the mechanical characteristics of the surface, LUCCHINI 2343 can be coated with
PVD or PA/ CVD methods.
Alternatively it can be subjected to nitriding: this allows a hardness value of the nitrided layer up to about 900-
1000 HV.
