O6 is an oil-hardening graphitic tool steel with excellent non-deforming properties. Free graphite in its structure affords exceptional free-machining properties. The combination of graphite and hard carbides gives O6 tools excellent resistance to adhesive wear (galling) in applications such as ring gauges, plug guages, and bushings.
Typical applications include: Blanking Dies, Guages, Draw Dies, Bushings, Perforating Dies, Punches.
Typical chemistry: Carbon 1.50% * Manganese .75% * Silicon 1.00% * Molybdenum .30%
