Oil Hardening Cold Work Tool Steel
O-6 Tool steel is noted for it's excellent wearing and galling resistance in metal on metal sliding applications. O-6 is an oil-hardening graphitic cold work tool steel. The tiny graphite carbon particles are distributed evenly throughout the tool steel essentially create a self-lubricating effect which results in outstanding machinability and non-seizing characteristics. The graphite also helps retain oil where lubrication is used. For an oil-hardening steel, 06 holds size well during heat treating.
Properties
O-6 is typically bought to meet chemistry requirements rather than physical requirements. For that reason, physical properties are generally not provided unless requested prior to production. Any material can be sent to a third party after production to be tested for physical properties.
Typical Uses
Typical Applications for O-6 Tool Steel include:
- Blanking Dies
- Piercing Dies
- Drawing Dies
- Pneumatic Hammers
- Forming Dies
- Spinning Tools
- Punches
- Stamps
- Gauges
- Wear Plates
- Cams
- Rotary Slitting Cutters
