Cold drawn steel wire (English name: wwe2) is to increase the yield point strength of steel bars to save steel, and the tensile stress exceeds the original steel bar yield point strength.
Cold-drawn steel bars are hot-rolled steel bars subjected to cold processing, which have high hardness and poor toughness, which improves the yield point strength of the steel bars, saves steel, and also meets the needs of prestressed reinforced concrete structural steel bars. Cold drawn low carbon steel wire is divided into two grades according to mechanical properties. Grade A steel wire is mainly used for small prestressed components, and Grade B steel wire is used for welding or tying skeletons, meshes or stirrups.
