Product Description

 Qilu ASTM A8 Mod Cold Work Tool Steel Round Bar/Plate

 

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.

Annealing

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

Quenching 

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

     Quenching hardness : 59-62 HRC

Tempering 
    Tempering temperature / ºC : 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.
