    A-10 Graph-Air® Annealed

    Tool & Die Steel PRODUCT

    PACIFIC A10 contains graphite particles distributed throughout the microstructure which gives it excellent machinability and good anti-seizing characteristics. Because of hardening from low temperature (1450/1500°F), its size change and distortion characteristics are both very low. A10 is perhaps the most stable of all tool steels through heat treatment.

    FORGING:
    Preheat at 1200/1250°F before raising to 1800/1925°F forging temperature. Do not forge below 1600°F.

    ANNEALING:
    Heat slowly and uniformly to 1410/1460°F and soak before cooling at a maximum rate of 15°F per hour to 950°F (cooling rate below 950°F is not critical). Typical annealed hardness is 235/269 HB.

    STRESS RELIEVING:
    Heat to 1200/1250°F and hold 1 hour minimum at temperature; cool in air.

    HARDENING:
    Preheat at 1200/1250°F before raising to an austenitizing temperature of 1450/1500°F; hold at temperature 30 to 60 minutes. Cool in air (to 80/90°F for maximum hardness); typical as quenched hardness is 62/64 HRC.

    TEMPERING (Drawing):
    Temper immediately at 350/800°F to an approximate hardness range of 62 to 55 HRC. Double tempering is suggested with cooling to room temperature between tempers.
