    O-1 Annealed

    Tool & Die Steel PRODUCT

    PACIFIC O1 is a general purpose, relatively non-performing grade which hardens from low temperatures (smaller tools and dies can be heated with a torch). When greater stability in heat treatment and/or wear resistance is required, consider PACIFIC A2. If machinability is of prime importance, consider Graph-Mo? (06).

    FORGING:
    Heat to 1800/1950°F, do not forge below 1550°F.

    ANNEALING:
    Heat to 1400/1450°F and hold 1 to 4 hours depending on part size, cool at a maximum rate of 40°F per hour to 1000°F (cooling rate below 1000°F is not critical). Typical annealed hardness is 183/212 HB.

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

    HARDENING:
    Preheat at 1200°F. Austenitize at 1450/1500°F for 10 to 30 minutes. Quench in oil to an expected hardness of 63/65 HRC.

    TEMPERING (Drawing):
    Temper at 350/500°F for an hour at temperature to approximate hardness of 62 to 57 HRC. Usually, when greater toughness is required than can be obtained by tempering above 500°F, it is customary to use a shock resisting tool steel such as PACIFIC S7.
