METTALURGICAL COMPOSITION AND WEAR RESISTANCE COMPARISON CHART

This selection of cold forming tool steels includes the conventionally produced steels as well as two types of Crucibles' CPM type steels; commonly used for high performance applications where minimal wear is nessecary to achieve minimal down time and maximum production. These are the toughest steels available and will out perform all else.

We offer complete consoltation in selecting composition, as well as angles and edges for your specific applications. Let J.Wenning Grinding & Supply Inc help you run more efficiently. In turn Saving you MONEY....
