Stainless steel coil is a rolled material made of stainless steel, typically with a thickness ranging from 0.3mm to 6mm. It possesses excellent corrosion resistance, high strength, and ease of cleaning, making it widely used in various fields.
The production process of stainless steel coil generally involves the following steps:
Raw material preparation: The raw material for stainless steel coil is typically stainless steel sheet or strip, with a thickness ranging from 0.3mm to 6mm.
Cutting: The stainless steel sheet or strip needs to be cut to obtain the desired length of stainless steel coil.
Hot rolling: The stainless steel sheet or strip is placed into a rolling mill and processed through heating and rolling to form a stainless steel coil. During the rolling process, the rollers of the mill apply pressure, causing the stainless steel sheet or strip to undergo plastic deformation in the rolling direction, gradually forming a stainless steel coil.
Cooling: After rolling is completed, the stainless steel coil undergoes a cooling treatment to achieve the desired mechanical properties.
Surface treatment: The surface of the stainless steel coil requires treatment to enhance its surface quality and corrosion resistance. Common surface treatment methods include pickling and electroplating.
Inspection: After the production of the stainless steel coil is completed, it undergoes inspection to ensure it meets the required quality standards and performance requirements.

Stainless steel strip is produced through the cold rolling process. The specific production process involves the following steps:
1. Raw material preparation: The raw material for stainless steel strip is typically stainless steel coils, with a thickness ranging from 0.3mm to 6mm.
2. Hot rolling: The stainless steel coils are placed into a rolling mill and processed through heating and rolling to form stainless steel strips. During the rolling process, the rollers of the mill apply pressure, causing the stainless steel coils to undergo plastic deformation in the rolling direction, gradually forming stainless steel strips.
3. Cooling: After rolling is completed, the stainless steel strips undergo a cooling treatment to achieve the desired mechanical properties.
Cutting: The cooled stainless steel strips are cut to the required length.
4. Surface treatment: The surface of the stainless steel strips requires treatment to enhance its surface quality and corrosion resistance. Common surface treatment methods include pickling and electroplating.
5. Inspection: After the production of stainless steel strips is completed, they undergo inspection to ensure they meet the required quality standards and performance requirements.
Applications
304 stainless steel plate and 201 stainless steel plate are two common stainless steel materials, and their main differences lie in chemical composition, physical properties, processing performance, and price.
Chemical composition: The main composition of 304 stainless steel is chromium (Cr) 18-20%, nickel (Ni) 8-10.5%, manganese (Mn) 2.5-3.0%, silicon (Si) 1.0-3.0%, phosphorus (P) ≤0.035%, sulfur (S) ≤0.030%, and chromium-nickel-molybdenum (Mo) 2.5-3.5%.
While the main composition of 201 stainless steel is chromium (Cr) 18-20%, nickel (Ni) 8-10.5%, manganese (Mn) 2.5-3.0%, silicon (Si) 1.0-3.0%, phosphorus (P) ≤0.035%, sulfur (S) ≤0.030%, and chromium-nickel-molybdenum (Mo) 2.5-3.5%.
As seen, although the main composition of the two stainless steels is similar, there are slight differences in their chemical compositions, which also lead to differences in their performance.
Physical properties: Due to the differences in chemical composition, the physical properties of the two stainless steels are also different. For example, 304 stainless steel is more resistant to high temperatures, corrosion, and wear than 201 stainless steel. Additionally, the density of 304 stainless steel is higher than that of 201 stainless steel.
Processing performance: Since 304 stainless steel has higher hardness and strength, it is more difficult to process compared to 201 stainless steel. This means that more energy and time are required to complete the same tasks during the processing.
Price: As the chemical composition and performance of 304 stainless steel are superior to 201 stainless steel, its price is relatively higher. In the market, the price of 201 stainless steel is usually lower than that of 304 stainless steel.
In conclusion, although the chemical composition of the two stainless steels is similar, they have differences in physical properties, processing performance, and price.
