The composition of Duplex Steel S32205 Nuts includes around 22% chromium, 5–6% nickel, 3% molybdenum, and a trace amount of nitrogen, which together create a well-balanced microstructure of ferrite and austenite. This unique blend results in remarkable mechanical properties, such as high tensile and yield strength, excellent toughness, and outstanding resistance to pitting, crevice, and chloride stress corrosion. These nuts are designed to maintain their stability and integrity, even when faced with high pressure and elevated temperatures.
