Zhengye Steel wire rod(s) is also called wire rod, which usually refers to small-diameter round steel in a coil. The diameter of the wire rod is in the range of 5-19mm (usually 6-9mm), and the lower limit is the minimum size of the hot-rolled steel section. There are many varieties of wire rods. Low carbon steel wire rods in carbon steel wire rod(s) are commonly called soft wires, and medium and high carbon steel wire rods are commonly called hard wires. Wire rods are mainly used as blanks for wire drawing, and can also be directly used as building materials and processed into mechanical parts. Stainless steel wire rod(s) are used in the manufacture of stainless steel wire, stainless steel spring steel wire, stainless upset forging steel wire and steel wire for stainless steel wire rope. With the advancement of production technology, wire rods with square, hexagonal, fan-shaped and other special-shaped sections have appeared; the upper limit of diameter has been expanded to 38 mm; the weight of the coil has increased from the original 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 thinned, and the structure and performance have also been greatly improved.
