Duplex Steel Bolts are made from duplex stainless steel grades such as S31803 and S32205. These alloys contain 22–25% chromium, 4–7% nickel, 3–5% molybdenum, and nitrogen. This composition gives the bolts a tensile strength of 620–880 MPa and yield strength of 450–550 MPa. The bolts offer strong resistance to chloride-induced stress corrosion cracking, crevice corrosion, and pitting. They maintain structural integrity in high-pressure and high-temperature environments. Their hardness falls between 25–35 HRC, and they have excellent fatigue and impact strength, making them suitable for both dynamic and static loading.
