①soft - Wire is subjected to bright heat treatment, or after heat treatment, it undergoes pickling or similar processes to remove surface scale.
②Lightly drawn- Wire is drawn to finished dimensions with a small reduction in cross-section after heat treatment.
③Cold drawn - Wire undergoes conventional drawing after heat treatment, which is the process of forming at room temperature through methods such as die drawing or roll drawing.
