    Delivery Condition

    EAF+(ESR) or EAF+LF+VD+(ESR), Hot rolled or Forged, Annealed, Hardness≤235HB,

    Black surface or Machined surface (Peeled, Turned, Grinded), UT 100% Passed


    Characteristics

    1. A kind of air hardening tool steel.

    2. Good toughness with medium wear resistance and relatively easy to machine.


    Applications

    Steel Grade AISI A2 is usually used for making cutting tools (dies and punches),

    blanking and punching tools, thread rolling dies, shear blades, trim dies, forming dies, gauges, stamping dies etc..


    ◆ Heat Treatment

    Annealing

    800 to 850°C

    Slow controlled cooling in furnace at a rate of 10 to 20°C/hr down to approx. 600°C,

    further cooling in air.

    Hardness after annealing: max. 235 HB.


    Stress relieving

    Approx. 650°C

    Slow cooling in furnace.

    Intended to relieve stresses set up by extensive machining, or in complex shapes.

    After through heating, hold in neutral atmosphere for 1 - 2 hours.


    Hardening

    950 to 980°C

    Oil, salt bath (200 to 250°C or 500 to 550°C), air blast, still air.

    Tools of intricate shape or with sharp edges should preferably be hardened in air or

    salt bath.

    Holding time after temperature equalization:15 to 30 minutes.

    Obtainable hard ness: 63 - 65 HRC


    Tempering

    Slow heating to tempering temperature immediately after hardening/time in furnace

    1hour for each 20 mm of workpiece thickness, but at least 2 hours/cooling in air.

    For average hardness figures to be obtained, please refer to the tempering chart.

    For certain cases we recommend to reduce tempering temperature and increase

    holding time.
