S-1, S-5, S-7 Shock Resistant Tool Steel
Description
S-1 Shock-Resisting tool steel is a medium-carbon steel which combines moderate hardness with good impact toughness. It is a deep-hardening, oil-hardening steel designed for shock and impact loading applications. S1 exhibits better resistance to abrasive wear than any of the other "S"-type shock-resisting steels.
S-5 Shock-Resisting tool steel is a silicon-manganese tool steel which exhibits the highest impact toughness among all of the "S" type steels. The high toughness and the ability to be hardened to 62 Rockwell C make S-5 an excellent choice for applications which require higher strength than S-7 shock-resisting tool steel. The steel is typically hardened using an oil quench, but for simple geometries, the steel may be water quenched.
S-7 S7 Shock-Resisting tool steel is an air or oil hardening tool steel that is characterized by very high impact toughness. The combination of strength and high toughness makes S-7 tool steel a candidate for a wide variety of tooling applications. S-7 tool steel can be used successfully for both cold and hot work applications.
