It is of paramount importance that tool steels or components should receive good and careful heat treatment. The performance of three similar die-casting dies is illustrated graphically as follows:

The costs of producing the three tools were:

The total cost per 1,000 die castings for the three dies is:
| H 13 correctly heat-treated $100 | H 13 incorrectly heat treated $333 | Steel inferior to H 13 correctly heat-treated $180 |
The cost of heat-treatment, in the above examples, is less than 10% total cost, incorrect heat-treatment reduced the life of the tool 75% and increased the tooling cost by $233 per 1000 castings or on 30,000 castings by $6,990.10.
What is the value of good heat treatment?
What is it worth to know that a tool has been correctly heat-treated in the latest and best equipment by specialists in the field.
The effects of poor heat treatment are not always evident to the eye, but are frequently demonstrated by a reduction in performance.
