Duplex steel tubing is crafted from duplex stainless steel, which cleverly merges the benefits of austenitic and ferritic stainless steels, resulting in high strength and remarkable corrosion resistance. It stands out with its excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, even in harsh, chloride-rich environments. Duplex steel tubing boasts impressive tensile and yield strength, good toughness, and dependable weldability. Its well-balanced microstructure enables it to perform effectively in both high and low-temperature conditions while ensuring durability in challenging applications.
