Introduction to stainless steel plate surface types and applications

Stainless steel plate surface types
Stainless steel plate surface treatment is an important link in the stainless steel plate production process. Usually, the surface types of stainless steel plates can be divided into the following types:
1. 2B: This refers to the surface of the stainless steel plate after cold rolling and annealing treatment. Its surface is relatively rough and is suitable for some occasions that do not have high surface requirements, such as making pipes, storage tanks, etc.
2. BA: BA surface refers to the surface state obtained by bright rolling. The surface is smooth and flawless. Its appearance is similar to silver. It is suitable for making decorations, kitchen appliances, etc.
3. NO.1: NO.1 surface refers to the hot-rolled surface state. There is a certain oxide film on the surface. It is smoother than the 2B surface. It is suitable for making transportation equipment, towers, chemical equipment, etc.
4. NO.4: NO.4 surface refers to the polished surface, which is smooth and delicate. It is suitable for making parts, tableware, elevator doors, etc. that require high processing precision.

The importance and influencing factors of surface treatment of stainless steel plates
The importance of surface treatment of stainless steel plates is self-evident. In addition to affecting the appearance of the product, it is also directly related to its service life and quality stability. The influencing factors on the surface of stainless steel plates mainly include the following aspects:
1. Equipment and equipment maintenance: Different surface treatment methods require the use of different equipment. For example, the 2B surface needs to be treated with cold rolling annealing equipment, while the BA surface needs to be treated with bright rolling equipment.
2. Materials and material preparation: The composition and preparation process of stainless steel plate materials will also have a direct impact on the surface treatment of stainless steel plates, so the selection of materials and preparation processes is very important.
3. Process control: Process control is one of the keys to the surface treatment of stainless steel plates, which includes rolling temperature control, reduction control, polishing time control and other aspects.

Application of stainless steel plate surface types
Different stainless steel plate surface types are suitable for different occasions. Common applications for different surface types are listed below:
1. 2B surface: suitable for making products with low appearance requirements, such as storage tanks, coolers, etc.
2. BA surface: suitable for making precision instruments, kitchen equipment, electronic appliances and other products.
3. NO.1 surface: suitable for making bridges, towers, oil tanks, forklifts and other equipment.
4. NO.4 surface: suitable for making tableware, decorations, elevator doors and other products.

In short, the surface treatment of stainless steel plates is an important link that affects the quality, appearance and service life of stainless steel plates. Different surface treatment methods can meet the needs of different fields. In actual production, appropriate materials and surface treatment methods should be selected, and the process flow and quality management should be strictly controlled to ensure the quality and application effects of stainless steel plate products.
