Adopting optimized integrated processes including precision smelting, hot extrusion and cold rolling, the newly upgraded stainless steel pipe series features outstanding high-temperature resistance, extreme corrosion resistance and stable mechanical performance. Covering super duplex steel, high-nitrogen non-magnetic steel and super austenitic steel grades, the products fully meet the stringent requirements of deep-sea oil and gas exploitation, new energy power generation, semiconductor fluid systems and high-precision industrial equipment.

With reliable product consistency and ultra-high structural stability, the localized high-end stainless steel pipes have replaced imported alternatives in batches. The technological upgrade effectively reduces the procurement cost of core industrial tubular materials, further consolidates the independent and controllable level of China’s high-end manufacturing chain, and strengthens the international competitiveness of domestic special steel products in the global market.
