    Material

    AISI O-1
    ​​​​​

    A general-purpose oil-hardening tool steel that is versatile and suitable for a wide variety of cold work applications.


    HARDENING:


    Preheating Temperature: 1110-1290 ° F (600-700 ° C)


    Austenitizing Temperature: 1450-1560 ° F (790-850 ° C)


    Protect the part against decarburization and oxidation during hardening. Quench as quickly as possible. Cooling must be uniform and at a rate to avoid distortion and/or quench cracking. Choose the temperature from the tempering graph. Temper twice with intermediate cooling to room temperature. Lowest temperature 360 ° F (180 ° C). Holding time at temperature minimum 2 hours.


    Available in 18” and 36” lengths.
