  • Quick Details

    1: AISI A36 steel introduction

        A36 is a mild steel. It has a final tensile strength of 58 and a yield tensile strength of 36. A36 is relatively ductile and can be stretched to about 20% of its original length during tensile testing. Its ductility and strength also give it good impact strength at room temperature.

    4: AISI A36 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. AISI A36 Steel Heat Treatment

          Hardening, which takes place in the range 788 °C to 816 °C

         Stress relieving, which takes place in the range 677 °C to 927 °C

    7: Delivery condition

        For hot forged  bar, usually the delivery condition is hot forged, annealed/QT, rough turned/Black surface.

        For hot rolled bar, usually the delivery condition is hot rolled, annealed/QT, Black surface.
