Detailed Description of Steel Wire Products
Steel wire is a coiled steel product made from hot-rolled wire rod through cold drawing, warm drawing or cold rolling. It is one of the four major steel varieties (plate, pipe, section, wire), featuring high strength, good toughness and diverse specifications, and is widely used in industrial, construction, civilian and other fields. On the basis of the original content, the detailed parameters of material models and dimensions are supplemented below to ensure the product information is complete and verifiable.
