5. Reducing risks during heat treatment
5.1 Origin of the problem

Context
For the parts that make up the mold, steel is generally heated by conduction, followed by radiation for higher temperatures. The outer layer of the part is always hotter than the core: thermal expansion is faster in the outer zone of the part. For the same reason, if the part has thickness differences, the thinner zones undergo thermal expansion more rapidly. These differences in expansion generate stresses in...
