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.

Treatment | Temperature Range | Cooling/Quenching | Notes |
---|---|---|---|
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) | In water. In 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. |
