This particular grade of tubing is celebrated for its near-equal blend of austenite and ferrite in its microstructure, primarily composed of chromium, nickel, molybdenum, and nitrogen. This balanced composition grants it an outstanding combination of high strength and impressive toughness. It offers remarkable resistance to stress corrosion cracking, along with excellent performance against pitting and crevice corrosion, making it significantly more robust than standard stainless steels while retaining good weldability.
