General knowledge of wire

The wire rod is a section steel according to its cross-sectional shape, and in fact it has become an independent type of steel. Hot-rolled round steel with a diameter of 5-4mm and rebar with a diameter of less than 10mm are generally called wire rods. Wire rods are mostly coiled into coils for supply by coiling machines, so they are also called wire rods or coils.　　

Wire rod is one of the steel varieties with a large consumption. After rolling, it can be directly used for reinforcement of reinforced concrete and welded structural parts, and it can also be used after reprocessing. For example, it is drawn into steel wires of various specifications, then twisted into steel wire ropes, woven into steel wire nets, wound to form and heat treated into springs; hot and cold forged into rivets and cold forged and rolled into bolts and screws; Cutting into heat treatment to make mechanical parts or tools.

Wire rods are generally made of ordinary carbon steel and high-quality carbon steel. According to different steel distribution catalogues and uses, wire rods include ordinary low-carbon steel hot-rolled round wire rod, high-quality carbon steel wire rod, carbon welding rod wire rod, quenched and tempered threaded wire rod, wire rod for wire rope, and wire rod for piano wire And stainless steel wire rod and so on.
