As the mould life expectative is high (in some cases exceeding 10 years), the most important properties of such materials are related to the surface integrity which is affected by the material processing characteristics such as polishability, machinability and heat treatment response.
The mould steel machinability is influenced not only by the mechanical and physical steel properties, related to its chemical composition and microstructure, but also by the production processes utilized in its fabrication [4].
On the other hand, polishability is a measure of how easy it is to perform surface polishing in tool steel, being affected by various metallurgical factors.
