CarTech S2® tool steel is a water hardening steel possessing extreme toughness. Even at Rockwell C 59/60, it will bend before it breaks. When hardened in medium and large size sections, CarTech S2 tool steel develops a hard case and a tough core. The combination of extreme toughness, hardness and wear resistance makes CarTech S2 tool steel suitable for use in many applications where other tool steels will not perform.

Applications:
CarTech S2 tool steel should be considered for tools or parts that require extreme toughness or must not break. Examples Include:

Punches
Knock-out pins
Clutch pins
Indexing pins
Trimming dies
Crimping dies
Swaging dies
Wrenches
Fingers
Shear blades
Heavy-duty forming tools
Heavy-duty coining dies
Special knurls
Stamps
Jaws

CarTech S2 tool steel has also found application in "battering tools," such as:

Pneumatic chisels
Vanstoning dies
Concrete breakers
Caulking tools
Rivet busters
Beading tools
Track chisels
Pipe cutter wheels
Screw drivers
Rivet sets
