Grades available in stock and via e-Techstore within 24 hours:

Corrosion resistant gradesCF-S18Z – Increased fracture toughness allows the usage of a submicron grade for applications where high bending forces occur.

CF-h25S – Fine-medium grade with high hardness and fracture toughness for high requirements regarding abrasive wear.

CF-h40S – the grade for universal application, ideal compromise between hardness and fracture toughness.

CF-F35Z – Fine-medium grade especially designed for bending, blanking and forming applications.

CF-20hP – medium-coarse grade combining the hardness of a fine grade with the fracture toughness of a coarse grade.

* minimal damage due to machining operation (formation of thermal cracks, white zone, ...) and low roughness values. adhesion due to ribbon material requires the best possible surface quality.

Optimisation of applicationstool improvement is the basis for maximum economy in the application process. CEratIZIt offers a systematic approach for the optimisation of the overall system. this includes both an application-specific grade selection

and the possibility to optimise the machining strategies in the production process in order to ensure sustainable development for other applications.
