The Welded 304/L Stainless Steel Tube, manufactured according to ASTM A249 / ASME SA249, is a high-performance austenitic stainless steel pipe designed for heat exchangers, condensers, and evaporators. Produced by Wuxi Korer Stainless Steel Co., Ltd., this tubing features a bright annealed surface, precise dimensional control, and excellent corrosion resistance. The low-carbon version, 304L, minimizes intergranular corrosion after welding and offers superior durability in high-temperature and corrosive environments. These tubes are widely used in power generation, petrochemical, food, and pharmaceutical industries.
