304L stainless steel precision tube is a low carbon version of 304, containing 18% chromium, 8% nickel, austenitic structure, non-magnetic. The surface is treated by mechanical polishing (MP), electrolytic polishing (EP) or bright annealing (BA), and the finish reaches Ra≤0.8μm (EP grade can reach Ra≤0.25μm).
304L stainless steel Mirror Finish tube has a low risk of intergranular corrosion after welding and is suitable for equipment that requires frequent welding. The smooth surface reduces bacterial growth and meets food and medical hygiene standards.
Application of 304L stainless steel Marine Grade tube
Food and medicine: milk, beverage delivery pipelines, pharmaceutical equipment (such as reactors, storage tanks).
Chemical environmental protection: pickling liquid pipelines, water treatment equipment.
Building decoration: high-end decorative pipes, furniture accessories.
