A Comprehensive Guide to 304 Stainless Steel Sheet in China
China is a leading global manufacturer and exporter of stainless steel, with 304 stainless steel sheet a particularly prominent product. This guide delves into the properties, types, and applications of 304 stainless steel sheet readily available from Chinese suppliers like Aoxing Metal (www.aoxingmetal.com), CIVMATS (www.civmats.com), and Tuolian (tuolianmetal.com). Understanding these aspects is crucial for selecting the appropriate grade for diverse projects.
Understanding 304 Stainless Steel Sheet
304 stainless steel sheet, also known as 18/8 stainless steel, belongs to the austenitic family. This designation indicates its composition: approximately 18% chromium and 8% nickel. These elements contribute significantly to its corrosion resistance, making it suitable for various applications. Companies like www.stainlesssteelmetalsheet.com offer a wide range of 304 stainless steel products. The sheet’s versatility extends to its formability; it can be easily shaped and welded, further enhancing its practical value.

FAQs
1. What is the difference between 304 and 304L stainless steel?
304L has a lower carbon content than 304, resulting in improved weldability and corrosion resistance, particularly crucial in applications involving extensive welding or exposure to corrosive environments. 304 offers slightly higher strength.
2. What are the common surface finishes for 304 stainless steel sheet?
Common finishes include 2B (a slightly dull, matte finish), BA (bright annealed, a smoother finish), No. 4 (brushed or satin finish), and 8K (mirror finish). The choice depends on aesthetic and functional needs.
3. How is the corrosion resistance of 304 stainless steel sheet affected by the environment?
304’s corrosion resistance is excellent in many environments. However, it can be compromised in highly corrosive environments, such as those with high chloride concentrations or extreme temperatures. Proper selection of grade (like 304L) is vital in such cases.
4. What are the typical dimensions available for 304 stainless steel sheet?
Standard sizes vary among suppliers, but common widths range from 20mm to 1540mm, and thicknesses from 0.22mm to 15.0mm. Custom sizes are often available upon request.
5. Where can I find reliable suppliers of 304 stainless steel sheet in China?
Several reputable Chinese suppliers offer 304 stainless steel sheet, including Aoxing Metal (www.aoxingmetal.com), CIVMATS (www.civmats.com), Tuolian (tuolianmetal.com), and www.stainlesssteelmetalsheet.com. It’s advisable to compare offerings and verify certifications before making a purchase.
