Currently, the two most common surface‑finishing treatments for 304L stainless steel coil on the market are BA and 2B.
Currently, the most common surface finishes for 304L stainless steel coils on the market are BA and 2B. Both of these finishes represent the original surface conditions as delivered from the mill. Thanks to its widespread use, excellent performance, cost-effectiveness, and outstanding formability, 304L stainless steel is highly favored by a broad range of customers. However, Wuxi Baoneng Stainless Steel would like to remind customers: when selecting 304L stainless steel coils, do not rely solely on the brightness or cleanliness of the surface to assess quality. For example, the new national standard specifies that 304L stainless steel contains 18%–20% chromium, which gives it superior strength and wear resistance; its nickel content of 8%–12% further enhances its corrosion resistance; and its carbon content is extremely low—below 0.03%—endowing 304L stainless steel with excellent resistance to intergranular corrosion.
304 stainless steel is one of the most widely used mainstream steels, prized for its excellent corrosion resistance. In contrast, 201 stainless steel exhibits relatively poorer corrosion resistance, resulting in differences in both its application areas and price compared to 304. Consequently, 201 is also less expensive than 304. In practice, some unscrupulous manufacturers, driven solely by profit, often pass off inferior materials as 304 stainless steel, thereby inflating prices and reaping excessive profits.
304 stainless steel boasts excellent corrosion resistance and heat resistance, with a service temperature range from –198°C to 800°C. It is not only suitable for household applications but is also widely used in the food industry. Another common grade, 316 stainless steel, builds on 304 by adding molybdenum, offering outstanding atmospheric corrosion resistance and superior high‑temperature strength. This makes it ideal for harsh environments, even capable of withstanding seawater exposure. Stainless steel railings and stair handrails are often made from this material, which is also extensively employed in watches, cameras, and other fields—adding yet another layer of seemingly quirky but entirely relevant trivia.

Let us introduce you to what aluminum tubing is.
Aluminum tubing typically refers to pipes made from aluminum alloys. Aluminum alloys are materials composed of aluminum combined with other metallic elements, characterized by their light weight, high strength, and excellent corrosion resistance, making them widely used across various industries.
Aluminum tubes are mainly classified into the following types.
Classified by precision: ordinary aluminum tubes and precision aluminum tubes; the latter typically undergo secondary processes such as cold drawing and rolling after extrusion.
With the rapid growth of the new‑energy vehicle industry, automotive thermal management systems are confronting entirely new challenges and opportunities. In this field, aluminum tubing, thanks to its superior performance and broad range of applications, has steadily emerged as an unsung leader in thermal management for new‑energy vehicles, providing robust support for enhanced vehicle performance and safe operation.
Production and Manufacturing of Aluminum Tubes
Aluminum tubes are classified into four main types based on their forming process: hot-extruded aluminum tubes (the mainstream), cold-drawn and precision-rolled aluminum tubes, welded aluminum tubes, and impact-extruded pharmaceutical aluminum tubes. Among these, the most widely used in the industry is seamless or split‑die extruded aluminum tubing.
What is the difference between 409 stainless steel and 430 stainless steel?
Compared with ordinary low‑carbon steel, 409 stainless steel sheet exhibits poorer thermal conductivity and lower elongation; consequently, greater deformation forces are required during shearing and bending. For 321 stainless steel sheet, springback during bending is more pronounced than in carbon steel. Moreover, since the elongation of stainless steel sheet is lower than that of carbon steel, the bend radius R of the workpiece should be larger than that for carbon steel during bending operations; otherwise, cracking is likely to occur.
What is the difference between 202 stainless steel and 304 stainless steel?
202 stainless steel and 304 stainless steel are both austenitic stainless steels at their core, non-magnetic, and visually quite similar. However, the key difference lies in their nickel content, which results in significant variations in their mechanical properties and price.
