The steel is composted of 1 percent carbon .3 percent silicon .6 percent manganese 5.3 percent chromium 1.1 percent molybdenum and .2 percent vanadium. The prefix A in the name designates it as an air-hardening steel.
Manganese steels have extensively application in industries due to good resistance to wear high work hardening capability with high toughness and ductility. Heat treatment is the main process to obtain desired mechanical properties and microstructure in this steel. The austenitizing temperature the austenitizing time and the rate of quenching are the main factors in heat treatment.
S5 Shock-Resisting Tool Steel. S5 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 S5 an excellent choice for applications that require higher strength than S7 shock-resisting tool steel.
