AISI O2
02 is an oil-hardening, nondeforming tool steel especially suited for general purpose toolroom work. It is safe to harden and shows little size change or warpage during the hardening operation. It is available as a decarb-free product. DCF bars have been cold finished in the mill eliminating the need for bar bark removal.
TYPICALAPPLICATIONS
Blanking Dies, Bushings, Forming Dies, Master Tools, Forming Rolls, Gauges, Trim Dies.

AISI O6
06 is an oil-hardening cold work steel which has outstanding machinability resulting from small particles of graphitic carbon uniformly distributed throughout the steel. These particles increase resistance to wear and galling in service. For an oil-hardening steel, 06 holds size well during heat treating.
TYPICALAPPLICATIONS
Blanking Dies, Piercing Dies, Drawing Dies, Pneumatic Hammers, Forming Dies, Spinning Tools, Punches, Stamps, Gauges, Wear Plates, Cams, Rotary Slitting Cutters.
