304L stainless steel coil is a low-carbon austenitic stainless steel (carbon ≤ 0.03%), containing 18%-20% chromium and 8%-10.5% nickel. Compared to 304 stainless steel, it offers superior resistance to intergranular corrosion and better weldability, making it suitable for applications in industries with high corrosion resistance requirements, such as chemical equipment, food machinery, and medical devices. Its excellent hot and cold formability allows it to be formed through processes like deep drawing and bending, with an operating temperature range of -196°C to 800°C.
