Stainless Steel 321 and 321H Electropolished Pipes are premium-grade piping products designed for applications requiring excellent corrosion resistance, high-temperature stability, and enhanced surface cleanliness. These titanium-stabilized austenitic stainless steels provide superior resistance to intergranular corrosion, even after exposure to high temperatures. The electropolishing process further improves corrosion resistance by creating an ultra-smooth, contaminant-free, and visually appealing surface. Known for their durability, hygiene, and precise dimensional accuracy, 321/321H electropolished pipes are widely used in pharmaceuticals, food processing, chemical plants, petroleum refineries, and high-temperature service environments where reliability, purity, and long-term performance are critical.
Stainless Steel 321 and 321H Electropolished Pipes contain chromium (17–19%), nickel (9–12%), and titanium for stabilization against carbide precipitation. Grade 321H features higher carbon content for improved high-temperature strength. Both grades offer excellent oxidation resistance up to 900°C. Electropolishing enhances the passive layer, resulting in improved corrosion behavior, reduced surface roughness, and minimal contamination risk. The pipes exhibit strong tensile strength, resistance to thermal fatigue, and reliable performance under cyclic heating. This combination of metallurgical stability and precision finishing makes them ideal for demanding industrial and hygienic applications.
