Shock Resisting Grades
S-grade tool steel are designed to resist shock at both low and high temperatures. A low carbon content is required for the necessary toughness (approximately 0.5% carbon). Carbide-forming alloys provide the necessary abrasion resistance, hardenability, and hot-working characteristics. This family of steels displays very high impact toughness and relatively low abrasion resistance, it can attain relatively high hardness (HRC 58/60). This type of steel is used in applications such as jackhammer bits.

Famous quotes containing the words shock, resisting and/or grades:
“I was not long since in a company where I wot not who of my fraternity brought news of a kind of pills, by true account, composed of a hundred and odd several ingredients; whereat we laughed very heartily, and made ourselves good sport; for what rock so hard were able to resist the shock or withstand the force of so thick and numerous a battery?”
—Michel de Montaigne (15331592)
“Jesus tapped me on the shoulder and said, Bob, why are you resisting me? I said, Im not resisting you! He said, You gonna follow me? I said, Ive never thought about that before! He said, When youre not following me, youre resisting me.”
