Stainless Steel 347 and 347H Electropolished Pipes Manufacturer, Supplier and Exporter in Amman, Jordan

Stainless Steel 347 and 347H Electropolished Pipes are high-performance, stabilized stainless steel piping solutions designed for environments where superior corrosion resistance, cleanliness, and heat stability are essential. Alloyed with niobium to prevent carbide precipitation, these grades offer outstanding reliability during high-temperature service. The electropolished finish enhances durability by creating a smooth, contaminant-free surface that improves fluid flow and resists corrosion more effectively. Because of their exceptional strength, precision, and hygienic properties, 347/347H electropolished pipes are widely used across chemical plants, pharmaceutical systems, food processing lines, refineries, and thermal processing applications requiring consistent, long-term performance.

Stainless Steel 347 and 347H Electropolished Pipes contain chromium (17–19%), nickel (9–13%), and niobium for stabilization against intergranular corrosion. Grade 347H features higher carbon content, providing improved strength at elevated temperatures. Both grades exhibit excellent resistance to oxidation up to 900°C and maintain structural stability under thermal cycling. Electropolishing reduces surface roughness, enhances the passive layer, and ensures minimal contamination absorption. These properties deliver high tensile strength, superior corrosion resistance, and dependable performance in aggressive or high-temperature environments, making them ideal for clean, demanding industrial processes.
