ESKYLOS 40 EVO
AISI: 28MnCrNiMo6.5.4.
SPECIAL AND INNOVATIVE PRE-HARDENED STEEL SUITED FOR THE MOST DEMANDING PLASTIC MOULDS ALSO FOR EXTREMELY LARGE SECTIONS IN ESR QUALITY
GENERAL CHARATERISTICS
ESKYLOS® 40 EVO is a special and innovative pre-hardened alloyed steel, suitable for the manufacture of big size injection moulds. ESKYLOS® 40 EVO represents the synthesis and the perfect balance of all the grades normally applied in this field and it is suited for a very wide range of applications in the plastics industry. Thanks to an accurate design of the chemical alloying elements and thanks to a special heat treatment, ESKYLOS® 40 EVO is characterized by a high degree of through hardening and it is suited in the case of large dimensions, that need its greater toughness balanced with very high hardness through to the core. ESKYLOS® 40 EVO represents one of the most important tough options, for highly resistant moulds that need very high pressure strength, excellent resistance to abrasion and a shorter machining time. The increasing in the use of synthetic and abrasive materials has led manufacturers to use ESKYLOS® 40 EVO
also when suitability for polishing and graining, combined with abrasion and compression resistance, are required. Due to its high level of micro-purity and micro-structural homogeneity, ESKYLOS® 40 EVO is very suitable for mirror polishing and guarantees excellent suitability to photo-engraving. Because of the low Carbon Equivalent content, the weldability level is excellent and ESKYLOS® 40 EVO becomes safer in case of welding repair.
