Cold Rolled Stainless Steel Strip
Description
Technical Parameters
Stainless steel strips are a kind of cold-rolled stainless steel product that typically measures under 5.00 mm in thickness and under 610mm in width. They are versatile products that are suitable for a wide range of applications. One of the most notable features of cold-rolled stainless steel strips is the various types of finish that are available. These finishes include the No.1 Finish, No.2 Finish, BA Finish, TR Finish, and Polished Finish.
The No.1 Finish is a rough, dull finish that is typically used for industrial applications where a smooth surface is not essential. The No.2 Finish is a slightly smoother finish that is popular in consumer products such as kitchen appliances. The BA Finish, also known as the Bright Annealed Finish, is a highly reflective finish that is used in decorative applications. The TR Finish, also known as the Non-Directional Finish, is a highly uniform finish that is often used in architectural applications. Finally, the Polished Finish is a smooth, mirror-like finish that is used for decorative purposes.
Overall, cold-rolled stainless steel strips are a versatile and high-quality product that is suitable for a wide range of applications. Whether you need a rough, durable finish for industrial use or a highly reflective finish for decorative purposes, you can find the perfect solution with the wide range of finishes available.
The available edges on cold-rolled stainless strips include No.1 edge, No.3 edge, and No.5 edge. These strips are categorized by series, including 200 series, 300 series, and 400 series.
Our customers love our range of stainless steel strips, which includes top sellers such as the 201 and 202 varieties, as well as the 301, 304 and 304L, and 316 and 316L options. We also offer high-quality 409, 410, and 430 stainless steel strips. Our selection comes in thicknesses ranging from 0.02mm to 6.0mm, with an incredible minimum tolerance of just 0.005mm. We take our metal seriously, and it shows in the quality of our products.

Finish for Cold Rolled Stainless Steel Strip
No.1 Finish:The material is rolled to the specified thickness, then subjected to annealing and descaling processes.
No.2 Finish:This finishing process, known as No.1 Finish, involves a final light cold-roll pass on rolls that are typically highly polished. Let me generate a highly similar content using a different approach to generate text based on the original information:
A final light cold-roll pass is often carried out after No.1 Finish to ensure optimal smoothness. This step is typically performed on rolls that have been meticulously polished to achieve a high level of shine.
Bright Annealed Finish:Final annealing in a controlled atmosphere furnace can help maintain a bright cold-rolled finish. By subjecting the material to this process, it is possible to retain the desired surface appearance and properties.
TR Finish: Cold-worked to obtain specified properties.
Polished Finish:No.3 and No.4 polished finishes are also offered for this product. This ensures that customers have the option to choose from a range of finishes that best suit their needs.
Note:
The appearance of this finish can range from a dull, matte gray to a relatively reflective surface, with the variation depending mostly on the composition. It is commonly used for parts that have undergone severe drawing or forming processes, as well as for applications where a brighter finish, such as the No.2 Finish, is not necessary. It finds great utility in parts that require heat resistance. To generate highly similar content by rearranging the given information, the following content can be considered:
This particular finish exhibits a range of appearances, spanning from a dull, matte gray surface to a relatively reflective one. Its visual characteristics are primarily determined by its composition. It finds extensive use in the manufacturing of parts that undergo severe drawing or forming processes. Additionally, it proves beneficial in applications where a brighter finish, such as the No.2 Finish, is not deemed necessary. Notably, this finish finds considerable application in parts requiring a high level of heat resistance.
Number two, referring to a finish that is characterized by its smooth and reflective surface, is commonly used in various applications such as household and automotive trim, tableware, utensils, and trays. The appearance of this finish varies depending on the composition used. Its versatility makes it a go-to option for general purposes.
The No.3 finish is characterized by a linear texture that can be achieved through mechanical polishing or rolling. The average surface roughness is typically within 40 micro-inches, and a skilled operator can effectively blend the finish. It's worth noting that surface roughness measurements can differ depending on the instrument, laboratory, and operator. Additionally, there may be some overlap between the surface roughness measurements for the No.3 and No.4 finishes.
Number 4 is a linearly textured finish that can be achieved through either mechanical polishing or rolling processes. The average surface roughness for this finish is typically up to 25 micro-inches. A skilled operator has the ability to blend this particular finish. It's important to note that surface roughness measurements can vary depending on the instruments used, the laboratories conducting the measurements, and the operators involved. There can be some overlap in the measurements of surface roughness between both number 3 and number 4 finishes.
The Bright Annealed Finish is a finish that is characterized by its smooth, shiny, and reflective appearance. This finish is typically achieved by cold rolling the material and then subjecting it to annealing in a protective atmosphere. This is done to prevent any oxidation or scaling during the annealing process, which could mar the look of the finished product. As a result of this process, the Bright Annealed Finish is a popular choice for many industries. It not only looks great but also offers enhanced corrosion resistance and durability, making it a reliable and long-lasting option for any application.
TR Finish— The finish resulting from the cold-rolling of an annealed and descaled or bright annealed product to obtain mechanical properties higher than that of the annealed condition. Appearance will vary depending upon the starting finish, amount of cold work, and the alloy.
Edges for Cold Rolled Stainless Strip
No.1 Edge: A rolled edge, either round or square as specified.
No.3 Edge: An edge produced by slitting.
No.5 Edge: An approximately square edge produced by rolling or filing after slitting.
