Metallographic Techniques for Tool Steels

TOOL STEELS can be prepared for macroscopic and microscopic examination using the same basic procedures used for carbon and alloys steels. However, because many tool steels are highly alloyed and are generally heat treated to much higher hardness than most carbon and alloy steels, specific aspects of their preparation differ slightly. The reasons for these differences and the required procedural modifications are discussed in the following sections. Also covered are the effects of hot working, composition, austenitizing, and tempering on microstructure.
