These nuts boast a well-balanced austenitic and ferritic microstructure, which boosts both their mechanical and corrosion-resistant qualities. The chemical makeup features high amounts of chromium, molybdenum, nickel, and nitrogen, providing remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, they show impressive yield and tensile strength, good impact toughness, and excellent fatigue resistance. This means they can hold their structural integrity even under high pressure, temperature changes, and aggressive chloride-rich environments.
