HS A4 Cold Work Die Steel
As modified cold work tool steel, HS A4 is improved high-toughness impact-resistant cold work die steel. It has fine and uniform ledeburite carbides, high toughness and impact resistance, and is not easy to crack when used for molds with complex shapes. The steel is a new generation of high-strength, high-impact cold-work die steel.

Application of HS A4
Cold stamping dies (home appliance punching die, gasket punching die, all kinds of connecting rod reed die, etc.), cold extruding dies (clutch, gear, flange plate and guide tube etc.), cold heading dies (cavity and punch pin, etc.), cold shear blade for plate.
Features of HS A4
Heat treatment hardness of this kind of cold work die steel is equivalent as that of D2 steel, and the toughness is more than 3 times of that of D2, while the wear-resistance is slightly lower than that of D2 steel.
Long service life under high stress impact
Cutting processing performance is better than that of D2 steel
