Wire rod is a long, slender metal bar, typically made of carbon steel, alloy steel, stainless steel, or other metal alloys, and is widely used across numerous industries including construction, automotive, electronics, furniture, and machinery manufacturing. Key characteristics of wire rod include high strength, good ductility, excellent wear resistance, and corrosion resistance. Its surface can be smooth or textured, depending on the manufacturing process and application requirements. During production, wire rod is precisely controlled in shape and dimension through processes such as hot rolling, cold drawing, or cold rolling. 20Cr13 stainless steel wire is a wire product made from martensitic stainless steel, which contains a relatively high chromium content (approximately 13%). 20Cr13 stainless steel wire is widely used in the manufacture of cutlery, springs, shafts, valves, and various high-strength components.
