GC-411CT

Grade Attributes

The relatively coarse carbide particle grain size coupled with medium binder content provides a wear resistant grade with moderate resistance to impact. The tantalum carbide addition ensures the highest resistance to galling.

The corrosion-resistant additive exhibits high resistance to binder leaching during the EDM process as well as preventing latent, residual corrosion that may occur on the working surfaces of tools being stored for future use.
