AISI SAE S-7 Hi-shock tool steel is an excellent chock steel that can be and is often used in hot work applications where the tool temperature does not exceed 1000 deg. F. This tool steel combines the qualities of high strength and good ductility for cold and medium hot work application.
AISI S7 is a shock resisting tool steel with excellent toughness and high strength, along with low to medium wear resistance. It has been widely used for many years to make chisels and punches which undergo shock loading, and has found increasing use for small plastic molds. AISI S7 is easy to machine in the annealed condition and can be readily heat treated. It is deep hardening and in many cases (except for large sections) it can be air quenched, exhibiting minimal distortion on hardening. Due to its relatively high attainable hardness (HRC 58/60) it offers high compressive strength (resistance to deformation) while retaining good toughness. Crucible S7 is a versatile tool steel for both cold and warm shock applications.
AISI S7 applications include:
- Chipping chisels
- Knock out pins
- Screw driver blades
- Circular pipe cutters
- Mandrels
- Shear blades
- Drift pins
- Punches
- Stamps
- Grippers
- Rivet sets
- Track tools
- Hand chisels
