ABSTRACT
In spite of the complexity, this chapter is shorter than the previous ones. First, because a large part of the content is already presented in Chapters 3 through 5, these are only referred to here, especially when considering the concepts and data on undissolved carbides, precipitation hardening, and retained austenite. Second, because of the decrease in application of high-speed steels. Being the main application filed in cutting tools for machining processes, the use of high-speed steel tends to decrease because of extensive substitution by other cutting tool materials such as cemented carbides. High-speed steels may also be employed in molds and dies, but the possibilities are limited by cost considerations, specifically material and heat treatment costs. The main applications of high-speed steels in molds and dies were already discussed in Chapters 4 and 5.
