Description

Product: AISI O*6

Key words: graphitic tool steel, tool steel, die steel, specialty steel, steel bar, hotwork, coldwork, forged bar, alloy tool steel, flat bar, round bar

Typical Analysis:
C: 1.***1.*5
Si: 0.***1.*0
Mn: 0.***1.*0
P: MAX 0.**0
S: MAX 0.**0
Cr: Max 0.*0
Mo: 0.***0.*0

Advantages:
***** non-seizing properties.
***** size stability for an oil hardening tool steel.

Availability:
Limited.

Applications:
O*6 has good size stability and excellent non seizing properties which make it a popular choice for metal on metal abrasive applications. Some typical choices are thread gages, draw dies, bushings, cam's and wear plates.

Machinability:
O*6 in the annealed condition has a machinability rating of *0% of a 1% carbon tool steel. It also has a good grindability rating.

Annealing:
O*6 should be atmosphere or vacuum annealed at ***0°F. Furnace cool to ***0°F, at approximately **0° per hour, then finish cooling in still air. This should result in a maximum Brinell hardness of **9.
