S-5 Shock Resisting Tool Steel
S-5 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.

AISI S5 Tool Steel-US
|Forging||1825-1925° F||Slow.||Cool slowly in furnace or in other insulating media.|
|Annealing||1450-1500° F||Cool slowly at a rate of 25° F per hour to 1000° F.||Hold at temperature for 2 hours.|
|Stress Relieving||1000-1250° F||Cool slowly||Stress relieve after rough machining|
|Preheating||1200-1250° F||Preheat time in furnace is ¾ Hr. per inch of thickness. Heating up to temperature as slow as possible.|
|Hardening||1575-1650° F (water)|
1600-1700° F (oil)
|Allow to cool to 125-150° F before tempering. Soak time is 10 minutes per inch of thickness. Minimum of 30 minutes. Oil quenching is preferred for intricate parts.|
|Tempering||(See Chart)||Temper immediately after hardening and quenching. For maximum hardness temper at 300-350° F. For maximum toughness temper at 900-1000° F.|
