Duplex Steel Welded Tubing is a unique material that offers the best of both worlds. Its composition, a carefully balanced mix of chromium, molybdenum, and nitrogen, provides a dual-phase structure. This special blend results in outstanding mechanical strength, superior resistance to corrosion, and excellent toughness, even under extreme pressure. Essentially, it gives you the robustness of ferritic steels with the enhanced corrosion resistance of austenitic grades, all in one durable tube.
