Economy calculation
It must be admitted that, at first sight, powder metallurgical high performance materials are relatively expensive. But often only at first sight. A detailed price/performance comparison between powder metallurgical and conventional tool steels often produces some surprising results.
An example of a cost-effectiveness study has revealed a saving of
EUR 12220 by the use of CPM® 10V material.
