In recent years, with the widespread application of stainless steel materials in the fields of construction, home appliances, medical treatment, chemical industry, etc., its surface treatment technology has also ushered in rapid development. Different treatment processes not only give stainless steel a diverse appearance, but also significantly improve its corrosion resistance, wear resistance and other properties, meeting the personalized needs of different scenarios.

Surface treatment technology is flourishing, performance and beauty are equally important

The surface treatment technology of stainless steel plates is mainly divided into several categories, including mechanical treatment, chemical treatment, electrochemical treatment and coating technology, each technology has its own characteristics:

Mechanical treatment-creating a variety of textures

Sandblasting: A matte surface is formed by high-speed sand impact, which is suitable for industrial equipment and architectural decoration, and can effectively hide scratches.

Wire drawing polishing: A fine hairline texture is formed, which has both wear resistance and beauty, and is commonly seen in elevators and high-end kitchenware.

Mirror polishing: A smooth surface with high reflectivity is mostly used for products with strong decorative properties, such as luxury goods and high-end home appliances.

Chemical treatment - improving corrosion resistance

Pickling + passivation: removing the oxide scale and forming a passivation film through acid, greatly improving corrosion resistance, suitable for chemical and energy industries.

Electrolytic polishing: using electrochemical dissolution technology to make the surface smoother and enhance corrosion resistance, it is an ideal choice for medical devices and food industries.

Electrochemical and coating technology - expanding the application boundaries

PVD coating: can generate colored stainless steel such as titanium and rose gold, which is highly decorative and wear-resistant, and is widely used in building curtain walls and high-end consumer products.

Nano coating: It has super hydrophobic and anti-fingerprint properties, suitable for electronic products, elevator panels and other scenes with high cleanliness requirements.

Industry trend: environmental protection and high performance go hand in hand

With the increasingly stringent environmental regulations, the wastewater treatment problems of traditional pickling and other processes have prompted companies to explore greener alternatives, such as laser surface treatment and environmentally friendly passivation technology. At the same time, consumers' demand for the beauty and functionality of stainless steel products continues to increase, promoting the popularization of high-end technologies such as PVD coating and anti-fingerprint coating.

Industry experts said that in the future, stainless steel surface treatment technology will develop in the direction of "high performance, low pollution, and personalization" to meet the dual standards of industrial durability and consumer market aesthetic needs.

Conclusion

The continuous innovation of stainless steel surface treatment technology is providing better solutions for all walks of life. Whether it is the corrosion resistance demand in the industrial field or the aesthetic pursuit of the consumer market, the diversified process selection will help stainless steel materials shine in more fields.
