Steel Wire Rod

There are many varieties of wire rods. The low carbon steel wire rod in the carbon steel wire rod  is commonly known as the soft wire, and the medium and high carbon steel wire rod is commonly known as the hard wire. Wire rods are mainly used as blanks for wire drawing, and can also be directly used as building materials and processed into mechanical parts.

With the advancement of production technology, square, hexagonal, fan-shaped and other special-shaped wire rods have appeared; the upper limit of the diameter has been expanded to 38 mm; the weight of the coil has increased from 40-60 kg to 3000 kg. Due to the development of a new post-rolling heat treatment process, the iron oxide scale on the surface of the wire rod has been significantly reduced, and the microstructure and properties have also been greatly improved.

Steel wire rod, The reduction of wire diameter is conducive to reducing further cold working processes, such as pickling, annealing times and drawing passes, reducing various consumption indicators and improving productivity. Therefore, users generally hope to obtain the thinnest wire diameter as possible. Usually the diameter of hot-rolled wire rod is mainly 6.0 and 6.5mm, the lower limit of Chinese standard is 5.5mm, and some countries can produce 5.0mm.
