Pickled steel coils

Pickled steel coils have the following characteristics:

Good Surface Quality

Thorough Removal of Oxide Scale: Through the pickling process, the oxide scale on the surface of hot-rolled steel coils can be effectively removed, making the steel surface cleaner and smoother, presenting a nice and sleek appearance. This significantly improves the surface quality and facilitates subsequent processing and treatment operations such as welding, oiling, and painting.

Uniform Surface Roughness: The surface roughness of the pickled steel coils is relatively uniform, which is beneficial for enhancing the adhesion of coatings and the appearance quality after painting. It makes the steel more durable during use and less prone to problems such as coating peeling.

High Dimensional Precision

Small Thickness Tolerance: The thickness tolerance of pickled steel coils is well controlled and can meet relatively strict dimensional precision requirements. During the processing, it can better ensure the consistency and stability of the product, reducing processing errors caused by uneven thickness.

Good Strip Shape: After operations such as tension leveling and flattening, the strip shape of pickled steel coils is improved. It can cause certain changes to the strip shape, thereby reducing the deviation of flatness, enhancing the surface finish, and strengthening the appearance effect. This is conducive to subsequent forming processing operations such as stamping and bending, reducing the rejection rate caused by poor strip shape.

Excellent Processing Properties

Good Stamping Performance: Pickled steel coils have good stamping performance, with good stretching effects and being less likely to break. They are suitable for processing various components that require stamping forming, such as the frameworks, wheels, and seats of automobiles. They can meet the forming requirements of complex shapes and high-precision dimensions, improving production efficiency and product quality.

Good Welding Performance: Since the surface oxide scale has been removed, pickled steel coils can achieve better welding results during welding. The weld quality is high, the welding strength is reliable, reducing the occurrence of welding defects and enhancing the stability and reliability of the welding structure.

Enhanced Corrosion Resistance

Oil Coating Protection: Usually, an oil coating treatment is carried out after pickling. A protective film is formed on the surface of the steel, which can effectively prevent the steel from coming into contact with air, moisture, etc. during storage and transportation, slowing down the corrosion rate of the steel, prolonging the service life of the steel, and reducing material losses and quality degradation caused by rust.
