What is Composition of Shock-resisting Steel - Definition

The principal alloying elements in shock-resisting steels, also called group S steels, are manganese, silicon, chromium, tungsten, and molybdenum, in various combinations. A low carbon content is required for the necessary toughness (approximately 0.5% carbon). Composition of Shock-resisting Steel

Shock-resisting steels are a specialized class of tool steels with very high impact toughness and relatively low abrasion resistance and can attain relatively high hardness (HRC 58/60). Shock-resisting steels are designated as Group S steels according to the AISI classification system. The high shock resistance and good hardenability are provided by chromium-tungsten, silicon-molybdenum, silicon-manganese alloying. The principal alloying elements in shock-resisting steels, also called group S steels, are manganese, silicon, chromium, tungsten, and molybdenum, in various combinations. A low carbon content is required for the necessary toughness (approximately 0.5% carbon). Type S1, S5, and S6 steels are oil quenched and type S2 steels are water quenched.

Group S steels are used primarily for chisels, rivet sets, punches, springs, dies for forging, and punches, and other applications requiring high toughness and resistance to shock loading.
