1. 2B surface
This is a surface obtained after cold rolling, heat treatment and pickling. Its surface is relatively smooth, but there may be slight straightening marks and a small amount of oxide scale residue. For example, some ordinary stainless steel products, such as stainless steel tableware, may use stainless steel coils with 2B surface as raw materials.
2. BA surface
This surface is obtained by bright annealing on the basis of 2B surface. It has high gloss and flatness and good reflective performance. It is often used for high-end stainless steel products, such as panels of high-end kitchen appliances.
3. 8K surface
A mirror-effect surface obtained by grinding and polishing. It has extremely high finish and reflectivity, and can clearly reflect the image of the object. Commonly used in architectural decoration, elevator cars and other occasions that require high reflectivity and beauty.
4. No.1 surface
This surface is obtained after hot rolling, heat treatment and pickling. The surface is relatively rough, with oxide scale and thick pickling marks. It is often used for industrial parts that do not have high requirements on the surface, but need to have certain strength and corrosion resistance.
5. Frosted surface
Through the frosting process, the surface presents a uniform frosted texture. It has a certain anti-slip and anti-fingerprint effect, and is often used in stair handrails, electrical appliance housings, etc.
6. Patterned surface
Through embossing, etching and other processes to form a specific pattern on the surface. It can increase the beauty and decorativeness of stainless steel coils, and is suitable for decorative materials and other fields.
Application of stainless steel coils in the industrial field
In the industrial field, stainless steel coils are widely used due to their excellent performance. For example, in the chemical industry, stainless steel coils can be used to manufacture containers and pipes for storing and transporting chemicals, and their corrosion resistance can effectively prevent the erosion of chemicals. Stainless steel coils can cope well with corrosive media such as strong acids and strong alkalis. In mechanical manufacturing, stainless steel coils are often used to manufacture various parts, such as shafts, gears, etc., and their high strength and wear resistance ensure the normal operation and long-term use of machinery.
Application in the field of construction
The application of stainless steel coils in the field of construction is also very common. Stainless steel coils are often used for the exterior decoration of buildings, such as curtain walls and roofs. Their unique metallic luster can give buildings a modern and beautiful look. And the durability of stainless steel coils enables buildings to maintain a good appearance during long-term use. In addition, stainless steel coils can also be used to make structural components of buildings, such as stair handrails, railings, etc., which not only provide safety guarantees, but also have good weather resistance.
Application in the field of bridges
Stainless steel coils play an important role in bridge construction. Since bridges are exposed to the outdoor environment for a long time and need to withstand wind, sun and various adverse weather conditions, the corrosion resistance and high strength of stainless steel coils make them ideal materials for manufacturing bridge railings, cables and other components. For example, some large suspension bridges and cable-stayed bridges use stainless steel coils for their key load-bearing components to ensure the safety and stability of the bridge.
Application in the home field
In terms of home, stainless steel coils also have many applications. Kitchen appliances such as sinks and stoves are often made of stainless steel coils because they are easy to clean, not easy to rust, hygienic and durable. Stainless steel coils are also used in some frame structures and decorative parts of furniture, adding a stylish and modern element to the home. For example, the legs of dining tables and chair frames made of stainless steel coils are both beautiful and sturdy.
The production process and flow of stainless steel coils vary depending on the equipment and processes of the production plant. Generally speaking, its production process mainly includes the following steps:
Steelmaking: Iron ore, coke and other raw materials are smelted at high temperature to obtain molten iron with a high carbon content. Then, impurities in the molten iron are removed by blowing oxygen and other methods, and its chemical composition is adjusted to obtain molten steel that meets the requirements.
Continuous casting: Molten steel is continuously injected into the crystallizer, and a slab of a certain thickness is formed through cooling and solidification. The width and thickness of the slab can be adjusted as needed.
Hot rolling: The slab is heated to a high temperature and then rolled through a rolling mill for multiple times, gradually reducing the thickness of the slab and increasing its length. The hot-rolled steel plate usually has higher strength and toughness.
Annealing and pickling: The hot-rolled steel plate is annealed to eliminate its internal stress and improve its plasticity and toughness. Then pickling is performed to remove the oxide scale and rust on the surface of the steel plate to make its surface smoother.
Cold rolling: The annealed and pickled steel plate is rolled again to further reduce its thickness and make the surface smoother. The cold-rolled steel plate usually has higher precision and surface quality.
Leveling: The cold-rolled steel plate is leveled to eliminate minor defects and unevenness on its surface and improve its surface quality.
Slitting: The leveled steel plate is cut according to the required size to obtain steel plate coils of different widths and lengths.
Packaging: The slit steel plate coils are packaged to protect their surface quality and facilitate transportation and storage.
It should be noted that in the actual production process, strict quality control and inspection are required for each link to ensure that the quality of the stainless steel coil meets the relevant standards and requirements.

The quality inspection of stainless steel coils is an important part of ensuring that products meet standards and meet customer needs. It mainly includes the following aspects:
1. Chemical composition detection
Through spectral analysis and other methods, the content of various elements in stainless steel coils, such as chromium, nickel, molybdenum, etc., is detected to determine whether it meets the corresponding grade standards. For example, the chromium content in 304 stainless steel should be 18% - 20%, and the nickel content should be 8% - 10.5%.
2. Mechanical property detection
Tensile test: Measure the tensile strength, yield strength, elongation and other indicators of stainless steel coils to evaluate their ability to withstand tensile loads.
Hardness test: Commonly used test methods include Rockwell hardness and Brinell hardness to understand the hardness characteristics of the material.
3. Surface quality inspection
Appearance inspection: Observe whether there are defects such as cracks, scratches, pits, rust spots, etc. on the surface of the stainless steel coil.
Roughness detection: Use a roughness tester to detect whether the surface roughness meets the requirements.
4. Dimensional accuracy detection
Thickness measurement: Use tools such as micrometers to measure the thickness of stainless steel coils at different positions to ensure that their thickness is uniform and within the specified tolerance range.
Width measurement: Measure the width of the coil to ensure that it is within the allowable deviation.
5. Corrosion resistance detection
Through methods such as salt spray tests, simulate the corrosion resistance of stainless steel coils in harsh environments and evaluate their corrosion resistance.
6. Nondestructive testing
Ultrasonic testing: Used to detect whether there are defects inside, such as inclusions, pores, etc.
Magnetic particle testing: Suitable for detecting surface and near-surface defects.
7. Grain size detection
Observe the grain size and distribution of stainless steel coils through a metallographic microscope to evaluate the uniformity and performance of their organizational structure.
Only after strict quality testing can stainless steel coils be safely and reliably used in various fields. For example, in the food processing industry, if the corrosion resistance of stainless steel coils does not meet the standards, it may cause food contamination; in the construction industry, if the dimensional accuracy is unqualified, it will affect the construction quality and aesthetics.
