Chapter 9: Shock-Resisting Tool Steels Available to Purchase

The shock-resisting tool steels, designated as group S steels in the AISI classification system, have been developed to produce good combinations of high hardness, high strength, and high toughness or impact fracture resistance. This chapter describes the alloying effects of silicon on the properties of shock-resisting tool steels. In addition, it discusses the compositions, characteristics, applications, advantages, and disadvantages of shock-resisting steels with and without tungsten.
