How to eliminate stainless steel tensile scratches

1. Tension scars produced during the stretching process

Stretching is a commonly used process in stainless steel processing, but it is easy to produce tensile marks during the stretching process. The formation of tensile scars depends to a large extent on the material and hardness of the stainless steel material, as well as the speed and number of stretches. Once tensile marks occur during the stretching process, it will have a great impact on the quality and aesthetics of the final product.

2. Chemical treatment to eliminate tensile scars

Chemical treatment to eliminate tensile marks is a commonly used method for stainless steel products. The specific steps are: first, the stainless steel products need to be ground, then treated with appropriate chemicals, and finally polished. Chemical treatment can remove surface strain, scale and impurities, making the surface smooth and bright. However, chemical treatment requires the use of chemicals, and attention must be paid to operational safety and waste disposal.

3. Mechanical polishing to eliminate stretch marks

Mechanical polishing to eliminate stretch marks is also a commonly used elimination method for stainless steel products. Common mechanical polishing tools include mechanical polishing machines, sandpaper, polishing pads, etc. The specific steps are: first, polish the stainless steel products, and then select different mechanical polishing tools for polishing according to different degrees of scratches and material hardness. Mechanical polishing can remove surface strain, but cannot remove scale and impurities. Mechanical polishing requires the selection of appropriate polishing materials and tools, and attention to operational safety is also required.

4. Laser cladding eliminates tensile scars

Laser cladding is a relatively advanced method to eliminate tensile marks on stainless steel products, and is mainly suitable for high-quality products. The specific steps are: first heat the stainless steel product to the appropriate temperature, and then use laser to process the surface. Laser cladding can remove surface strain, oxide scale and impurities, etc., and ensure the smoothness and finish of the product surface. However, laser cladding requires high-tech operations and is also costly.

5. Things to note

1>No matter which elimination method is used, it is necessary to accurately judge and analyze the material, hardness, stretch degree, etc. of the stainless steel products in order to choose the appropriate method.

2> Appropriate safety measures need to be taken during operation, such as wearing gloves, protective equipment, etc., to avoid physical harm during operation.

3> Waste disposal is also extremely important and needs to be classified and processed in accordance with relevant regulations.
