These Duplex Steel 2205 Nuts are crafted from a well-balanced microstructure of austenite and ferrite, typically featuring around 22% chromium, 5–6% nickel, and 3% molybdenum, along with some nitrogen. This unique blend offers exceptional protection against pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, these nuts boast high tensile and yield strength, nearly double that of standard austenitic stainless steels. They also demonstrate good toughness, fatigue strength, and reliable performance even under high pressure and varying temperature conditions.
