  • For example, in gray iron, its carbon exists in iron ore in graphite condition, the crack is often gray, soft and strong, simple filtering, suitable for casting. In white iron, its carbon and iron together into iron carbide, crack appears white, very strong and brittle quality, for the material of malleable steel. The alloy grade consists of various alloying elements with different compositions and structures.

  • The tensile strength of steel wire is high and the hardness is high. In the flattening process, the longitudinal movement resistance of steel wire per unit volume increases and the elongation decreases. The steel wire unit volume will move to the lateral resistance smaller, the width of the increase. On the contrary, the wire is easy to extend lengthwise, and its width decreases. This is the production of high steel wire hardness is easy to wide, small hardness, easy to stretch out of wide reasons. If the tensile strength deviation of steel wire is large, the hardness uniformity of steel wire strip is poor, the width difference of the billet rolled into large, will seriously affect the quality of the billet.
