I. Material Selection
The main material for carbon steel screws is carbon steel. When selecting the material, factors such as the strength and toughness of the screws need to be considered to meet the requirements of different application fields.
II. Raw Material Processing
In the raw material processing stage, the selected carbon steel materials need to undergo processes such as forging, drawing, and rolling to obtain the required screw raw materials.
III. Cold Bending
Cold bending involves stretching and deforming the screw raw materials to make them thinner and longer, and processing the head into a thread. Cold bending can be divided into multi-pass cold bending and single-pass cold bending.
IV. Heat Treatment
Heat treatment refers to heating and cooling the screws at high temperatures to improve the material structure and performance. Common heat treatment methods include annealing, normalizing, quenching, and tempering.
Carbon steel screws have the advantages of high strength, long service life, and corrosion resistance, and are widely used in construction, machinery, electronics, automotive, and other fields. Through the above production process, carbon steel screw products that meet the requirements of different fields can be manufactured.
