LUCCHINI 2340 ESR
W. Nr. 1.2340
NADCA GRADE E
THE NEW APPROACH IN THE WORLD OF HOT WORK TOOLS AND HIGHLY RESISTANT PLASTIC MOULDS IN ESR QUALITY
GENERAL CHARATERISTICS
Lucchini 2340 ESR 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 ESR has been expressly designed for tools that have to work in a wide temperature range without compromising toughness.
Lucchini 2340 ESR 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 ESR thanks to its high resistance to thermal fatigue and to high temperature wear. LUCCHINI 2340 ESR is the result of years of research and experimentation of Lucchini RS in the field of Hot Work Tool steels. Thanks to the quasi-isotropic properties of ESR quality, LUCCHINI 2340 ESR represents also 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.
