Duplex Steel S32205 (AUS36) Stud Bolts comprise approximately 22–23% chromium, 5–6.5% nickel, 3–3.5% molybdenum, and 0.14–0.20% nitrogen with minor quantities of manganese, silicon, and copper. The duplex structure that combines the austenitic and ferritic phases provides superior resistance to pitting and crevice corrosion, as well as stress corrosion cracking. S32205 stud bolts exhibit a tensile strength of 700–850 MPa, yield strength of 450–550 MPa, and demonstrate high toughness, excellent fatigue resistance, and good performance at high temperature and pressure; therefore, they are ideally suited for demanding marine, industrial and chemical applications.

Many different businesses use Duplex Steel S32205 stud bolts because of the bolts’ ability to withstand extreme conditions. These bolts are typically used in offshore oil rigs, subsea technology, and marine constructions that are constantly bathed in seawater and subjected to very rough environments. Other industries that commonly use Duplex Steel S32205 stud bolts include the oil and gas industry for applications such as pipelines, pressure vessels, heat exchangers, and any type of application involving high levels of stress placed on components. Chemical companies will often use these bolts in industries where equipment is exposed to high-temperature chemicals and high-pressure environments. Other areas in which S32205 studs are utilized include desalination facilities, turbine or power generation facilities, and all types of industrial equipment that must perform continuously under extreme stress or in areas where their life span is greatly diminished due to high levels of chloride exposure.
