Applications of 304 and 304L Stainless Steel Round Tubes
304 and 304L stainless steel round tubes are widely used in chemical, food processing, medical equipment, and construction industries. 304 stainless steel offers excellent corrosion resistance and is suitable for common acidic and alkaline environments; 304L, due to its lower carbon content, exhibits better corrosion resistance and high-temperature stability after welding. According to ASTM A312 standards, 304L stainless steel round tubes can withstand temperatures ranging from -200°C to +870°C and are commonly used in demanding applications such as chemical reactors, food production lines, architectural decoration, and medical devices.
