Stainless Steel Coil Surface Finish

Through different processing methods of cold rolling and surface reprocessing after rolling, the surface finish of 201 stainless steel coils can have different types.

The surface processing of stainless steel coils have NO.1, 2B, No. 4, HL, No. 6, No. 8, BA, TR hard, Rerolled bright 2H, polishing bright and other surface finishes, etc.

Let's take a closer look at the surface treatment of stainless steel coils.

1. Pickling: The first step in the surface treatment of stainless steel coils is pickling. Pickling is the process of treating the surface of a material with an acidic solution to remove contaminants such as rust, scale and oxides. The process involves immersing the coil in a bath of hydrochloric or sulfuric acid, which dissolves any impurities and keeps the surface clean.

2. Rolling: After the pickling process, the stainless steel coil is rolled to make the thickness and flatness uniform. The process involves passing the coil through a series of rollers that compress and shape the material. The roller can be adjusted to create different finishes, from matte to glossy.

3. Annealing: Next, the stainless steel coil is annealed during heat treatment. Annealing helps soften the material and increases its ductility, making it easier to form coils or other shapes. The annealing process involves heating the coil to a high temperature and then cooling it slowly over time.

4. Grinding: After the stainless steel coil is annealed, it is ground to create a smooth polished surface finish. This step involves using an abrasive tool to remove any burrs or imperfections and create an even surface. This produces an even and reflective surface finish.

5. Polishing: Finally, the stainless steel coil is polished to enhance the aesthetics. Polishing is a surface treatment process that involves polishing a material with a fine abrasive compound to create a lustrous and reflective effect. This step enhances the appearance of the stainless steel and creates a specular reflection.

Process of Production

The production process of stainless steel coil is: raw material preparation - annealing and pickling - (intermediate grinding) - rolling - intermediate annealing - pickling - rolling - annealing - pickling - leveling (finished product grinding and polishing) - cutting, packaging and storage .
