    1: AISI H11 steel introduction

        AISI H11 tool steel is a 5% chromium hot work tool steel that is represented by its excellent impact toughness. Chromium hot-work tool steels are designated as group H steels according to the AISI classification system, and specified in ASTM A681standard. The most commonly used chromium hot-work steels are H11 tool steel, h12 tool steel, and H13 steel, within the series from H1 to H19.

        H11 tool steel is a deep-hardening, air-hardening steel and H11 alloy steel could be deep hardened by heat treatment and air-quenching. That gives minimal size change during heat treatment. H11 how work steel also has super resistance to thermal fatigue cracking and superb resistance to gross cracking and thermal shock when water cooled in service.

    4: AISI H11 steel mechanical properties

        The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.

    6: Heat treatment

    Annealing
        Slowly heat to 843 – 898(1550-1650 F) then slowly Cool to 538(1000) in heat treatment furnace. Then frosty in make public. After annealing hardness HBS: 235 Max
    Hardening
        H11 steel having enormously high hardenability and should be hardened by cooling in yet appearance. The use of a salt bath or controlled mood furnace is desirable to minimize decarburization, and if not user-simple, pack hardening in spent arena coke is suggested. The temperature employed is usually 1800-1850F, depending upon size section.
    Quenching 
        Quenching temperature / ℃ | salt bath furnace: 996
        Quenching temperature / ℃ | controlled atmosphere furnace: 1010
        The heat preservation time/min: 5 ~ 15
        Quenching medium: air cooling .
    Tempering 
        Tempering temperature / : 552
        After tempering hardness HRC or future: 52


    7: Delivery condition
        For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.
        For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.

        For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
