... is much less costly than steel. It may not be cost-efficient to use cast iron dies for small parts due to the cost of pattern-making ( Ref 16.19 ). Wear and galling may limit the life of cast iron dies. To overcome this, selective (flame/laser) hardening, hard chrome plating, and/or adding inserts...
