  • Quick Details

    1: AISI A8 MOD steel introduction

       This steel is an improved steel of A8 steel, with good hardenability, toughness, heat treatment dimensional stability. Suitable for punches and cold forging dies with hardness requirements of 55-60 HRC. In addition, it is suitable for manufacturing non-metallic materials due to good hardness, wear resistance and toughness.

    6. AISI A8 MOD Tool Steel Heat Treatment


        Slowly heat to 870 – 890 ℃ , then slowly Cool to 500 ℃ in heat treatment furnace. Then frosty in make public. After annealing hardness HBS: 229 Max


        Quenching temperature / ℃ | outlet air cooling, oil cooling or air cooling : 1000 - 1050

         Quenching hardness : 59-62 HRC

        Tempering temperature / ℃ : 150 - 320

        After tempering hardness HRC or future: 53 - 60

    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.
