This tubing features a well-balanced microstructure of austenite and ferrite, which gives it both high mechanical strength and excellent corrosion resistance. With a composition rich in chromium, molybdenum, nickel, and nitrogen, it effectively guards against pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, the tubing offers high tensile and yield strength, great fatigue resistance, and solid toughness, ensuring it performs reliably under pressure, temperature fluctuations, and in harsh chloride-rich environments.
