ESKYLOS OPTIMO

NADCA GRADE E

TOP QUALITY ESR STEEL FOR LIGHT ALLOYS DIE CASTING APPLICATIONS

GENERAL CHARATERISTICS

ESKYLOS® OptiMo is the latest evolution proposed by Lucchini RS for the family of low Silicon steel grades, designed for the most demanding High Pressure Light Alloys (Al-Mg) Die Casting moulds. It has been developed starting from the experience of ESKYLOS® 2340 grade, optimizing the Molybdenum (Mo) content and adding special micro-alloying elements such as Tungsten (W) to improve characteristics.

ESKYLOS® OptiMo fully meets NADCA #207 specification concerning the annealed microstructure and banding segregation in the core of the block, the most critical position.

The impact capability testing is performed according to NADCA #207 specification, one of the most important worldwide reference for die-casting application.

Thanks to the optimized chemical analysis (P<0.0015%, S<0.003% and low secondary elements content), together with the Electro Slag Re-melting process, followed by special forging and specifically designed heat treatment procedures, ESKYLOS® OptiMo is able to achieve extremely high performances.
