Welcome To Wuxi Ontime Industrial Co., Ltd
Cold heading steel wire rod is generally low, medium carbon high-quality carbon structural steel, and high-quality alloy structural steel, used for cold heading forming to manufacture various mechanical standard parts and fasteners. In order to improve the plasticity and cold heading performance of the steel, the cold heading process requires high cleanliness and control of SI and Al content in the steel. Cold heading steel wire rod steel is generally low, medium carbon high-quality carbon structural steel, and alloy structural steel.
Cold heading steel, the cold heading is one or more impact loading at room temperature, widely used in the production of screws, pins, nuts, and other standard parts. Cold heading steel products are mainly used in automobile, shipbuilding, equipment manufacturing, electronics, home appliances, bicycles, tools, light steel structure, construction, and other industries.
