Stainless Steel Plate &Sheet Grade 201
Product standards
National Standard GB
American Standard ASTM
German Standard DIN
Japanese Standard JIS
Stainless Steel Plate &Sheet Grade 201 has two different manufacturing methods: cold and hot. According to the characteristics of the steel structure, it is classified into 5 categories. It is widely used in the fields of food and medical, chemical manufacturing, building decoration and vehicle and electrical appliances, and has a very wide range of applications.
Stainless Steel Plate &Sheet Grade 201 – cold processing
1. Color
The surface of the cold-rolled sheet is silver-white, which is commonly referred to as 2B surface.
2. Surface feel
The surface of the cold-rolled sheet is highly smooth with a glossy appearance, and it feels smooth and fine to the touch.
3. Plate dimensions
The standard dimensions of cold-rolled plates are 1219*2438mm, 1000*2000mm, and 1500*3000mm. The thickness ranges from 0.3 to 3mm. In special cases, there may also be cold plates with a thickness of 3-6mm. The main plate sizes are 1500*3000mm and 1800*3000mm.
4. Performance
Cold-rolled plates are produced through secondary processing based on hot-rolled plates. Therefore, cold-rolled plates have high hardness, high strength, and complex manufacturing processes, making them suitable for further processing.
5. Product Expansion
Cold-rolled plates can be further processed at the factory to be made into colored plates. For example, the rose gold stainless steel plates and imitation green bronze stainless steel plates commonly seen in shopping malls. The current processing techniques mainly involve electroplating and water plating. Specific details can be found in the relevant articles on the official website. They are suitable for direct on-site installation and use.
Stainless Steel Plate &Sheet Grade 201 – Hot processing
1. Color
The surface color of hot-rolled plates is relatively dark, usually brown in color. This is referred to as NO. 1 surface in professional terms.
2. Surface feel
The surface of the hot-rolled plate is an acid-washed surface, which is relatively rough and does not feel as smooth as that of the cold-rolled plate when touched.
3. Plate dimensions
The standard dimensions of hot-rolled plates are 1500*6000mm, 1800*6000mm, and 2000*6000mm. The thickness ranges from 3mm to 150mm. Special specifications for thickness and length can be customized for rolling production.
4. Performance
The intergranular distance of hot-rolled plates is relatively large. Compared with cold-rolled plates, they have lower hardness but higher ductility. They are suitable for processes such as secondary processing, shearing, bending, and sheet rolling.
5. Product Expansion
Hot-rolled plates are more suitable for undergoing further treatments such as painting or varnishing after on-site installation to achieve the desired effect.
