Stainless Steel 304/304L Sanitary Tubing is an austenitic stainless steel that combines chromium and nickel to enhance corrosion resistance and cleanliness. Typically, it contains about 18–20 percent chromium and 8–12 percent nickel, with 304L having a lower carbon content for better weldability. In terms of mechanical properties, this tubing boasts good tensile and yield strength, excellent toughness, and high ductility. It retains its strength across a wide temperature range and is resistant to oxidation, mild chemicals, and cleaning agents commonly used in sanitary settings.
