2B Surface Finished ASTM 201 304 430 Cold Rolled Stainless Steel Coil 0.2mm Thic

1. Appearance and surface treatment characteristics
2B stainless steel rolls have unique appearance and surface characteristics.
Its surface presents a matte state, after cold rolling processing and specific annealing treatment, the surface finish is high and has a certain soft texture.
This surface treatment makes the 2B stainless steel roll visually delicate, in sharp contrast to other metal materials with rough surfaces.
It has no obvious gloss reflection, which is very advantageous in some applications where light reflection is special.
For example, in some interior decoration or instrument equipment housing that needs to reduce glare.

2. Material composition and performance
2B stainless steel coil is mainly based on chromium (Cr), nickel (Ni) and other alloying elements of stainless steel material.
Among them, the chromium content is generally about 18%, and the nickel content varies from 8% to 10.5% according to different grades.
This alloy composition gives the material good corrosion resistance.
In a variety of corrosive environments, such as humid air, fresh water, weakly acidic solutions, etc., 2B stainless steel coil can form a dense chromium oxide protective film to prevent further corrosion reactions.
Its strength performance is also relatively excellent, the yield strength and tensile strength can meet the requirements of a variety of industrial and civil fields.
At the same time, it also has good ductility, in the processing process can be bent, stamping and other forming operations without fracture phenomenon,
This allows it to be machined into a variety of complex shapes to meet the needs of different designs and uses.

3. Processing performance
2B stainless steel coil has significant advantages in processing. Because its surface is relatively flat and smooth, the processing accuracy can be guaranteed when cutting, welding and other processing operations are carried out.
In the cutting process, whether it is using mechanical cutting or laser cutting, 2B stainless steel coil can obtain a relatively neat incision,
And it will not affect the subsequent processing quality because of the rough surface. In terms of welding, it is matched with suitable welding materials,
It can achieve a strong welding connection to ensure the strength and corrosion resistance of the welded joint.
In forming processing, such as rolling, bending and other operations, 2B stainless steel rolls can be smoothly changed according to the requirements of the mold and processing process.
Its good plasticity allows manufacturers to produce a variety of products such as stainless steel tableware, kitchenware, decorative plates and so on through stamping, drawing and other processes.

4. Application field
Architectural decoration field
In the construction industry, 2B stainless steel rolls are widely used for indoor and outdoor decoration. In terms of interior, it is often used for wall decoration board, elevator car interior decoration and so on.
Its matte surface can create a high-end, simple atmosphere, and blend with a variety of finishing styles.
In the outdoor, it can be used for part of the decoration of the building curtain wall, because its corrosion resistance can resist the erosion of natural environmental factors such as rain and dust, and keep the appearance clean and beautiful for a long time.
Industrial field
In the manufacturing of industrial equipment, 2B stainless steel coils are used to produce various types of containers, pipes, etc.
For example, in the food processing industry, containers used to store food are made with corrosion resistance and hygienic properties that meet food safety requirements.
In the chemical industry, some pipeline systems with high corrosion resistance requirements will also use 2B stainless steel rolls to ensure the safety and stability of chemical raw materials in the transportation process.
Household goods field
2B stainless steel coil is an important material for the production of household goods. As mentioned earlier, for the manufacture of stainless steel tableware, kitchenware, etc.,
Its good corrosion resistance ensures that it will not rust in the case of contact with water and food in daily use, and it is easy to clean and maintain.
At the same time, it is also used in some home decorations, furniture parts, etc., which provides beautiful and durable characteristics for home products.

5. Quality standards and testing
For 2B stainless steel rolls, there are strict quality standards. In terms of thickness, there are precise tolerance ranges to ensure consistency during processing and use.
Its chemical composition needs to comply with relevant international standards and national standards, and the content of main alloying elements such as chromium and nickel is accurately determined through advanced detection means such as spectral analysis.
In the surface quality inspection, visual inspection and surface roughness detection instrument are used to check whether the surface has scratches, pits and other defects.
At the same time, it will also carry out tensile tests and hardness tests on the mechanical properties of the material to ensure that its strength, ductility and other performance indicators meet the requirements, so as to provide users with high-quality 2B stainless steel coil products.
