Duplex S32205 is a nitrogen-strengthened duplex stainless steel containing about 22% chromium, 5–6.5% nickel, 3–3.5% molybdenum, and the balance iron. The microstructure is almost equal amounts of austenite and ferrite. This alloy provides it with superior resistance against pitting, stress corrosion cracking, and general corrosion. S32205 stud bolts have tensile strength of 95–115 ksi, yield strength of 65–80 ksi, and Rockwell hardness up to B100. Their high strength-to-weight ratio and resistance to corrosion render them a suitable option for hostile environments.

Duplex Steel S32205 Stud Bolts are used in marine engineering, offshore platforms, and chemical processing plants where there is high chloride exposure and mechanical stress. In oil and gas industries, they are suitable for pressure vessels, heat exchangers, and storage tanks. In desalination systems and pulp & paper mills, they provide resistance to pitting and crevice corrosion. Their corrosion resistance and strength also render them appropriate for use in power plant parts, pipelines, and water treatment plants. With better fatigue and impact strength, S32205 stud bolts guarantee long-term performance in structurally challenging and corrosive environments.
At Brian Fasteners, Duplex Steel Stud Bolts S32205 are meticulously packaged to ensure maximum protection and integrity during transit.
