LUCCHINI 2340
THE NEW APPROACH IN THE WORLD OF HOT WORK TOOLS AND HIGHLY RESISTANT PLASTIC MOULDS
GENERAL CHARATERISTICS
Lucchini 2340 is a high alloyed Chromium-Molybdenum- Vanadium Hot Work Tool steel characterized by a low Silicon content and by other special micro-alloying elements. Lucchini 2340 has been expressly designed for tools that have to work in a wide temperature range without compromising toughness. Lucchini 2340 is the ideal choice in hot applications where it is necessary to maintain unaltered the mechanical properties of the material in all the phases of the process, including the most critical moments on start-up. Constant development in hot processing technologies require the use of Lucchini 2340 thanks to its high resistance to thermal fatigue and to high temperature wear. LUCCHINI 2340 is demonstrating impressive resistance to fatigue in many applications and a significantly longer mould life than conventional Hot Work Tool steel grades.
