KEYLOS 40 EVO
DIN 28MnCrNiMo6.5.4
THE CUSTOMISED SOLUTION FOR PLASTIC MOULDS
GENERAL CHARATERISTICS
KEYLOS® 40 EVO is a special and innovative pre-hardened alloyed steel, suitable for the manufacture of big size injection moulds.
KEYLOS® 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, KEYLOS® 40 EVO is characterized by a high degree of through hardening and it is suited when is required greater toughness balanced with very high hardness through to the core.
KEYLOS® 40 EVO represents the best option for highly resistant plastic moulds that need very high pressure strength, excellent resistance to abrasion and a shorter machining time.
Because of the low Carbon Equivalent content, the weldability level is excellent and KEYLOS® 40 EVO becomes safer in case of welding repair.
