The main surface treatment methods for hot-rolled stainless steel coil are as follows:
Pickling: This chemical reaction removes scale, rust, and other impurities from the stainless steel surface, resulting in a smooth surface and improved corrosion resistance.
Polishing: This process uses polishing tools or chemical methods to smooth the surface, enhancing aesthetics and improving corrosion resistance.
Brushing: This process uses sanding belts or other abrasives to brush the stainless steel surface, creating a uniform texture that provides decorative and anti-fingerprint properties.
Electropolishing: This process uses an electrolytic reaction to smooth the surface and improve the corrosion resistance of the stainless steel.
Sandblasting: This process uses a high-pressure airflow to spray sand particles onto the surface, creating a uniform rough texture and is often used to improve surface adhesion.
Coating: This process, such as spraying anti-corrosion paint, painting, or laminating, can enhance the corrosion resistance and aesthetics of stainless steel.
These methods can be used individually or in combination to achieve the optimal surface finish for hot-rolled stainless steel coil.
