Istanbul, Turkey-based Yasin Fasteners is one of the leading manufacturers and suppliers of **S32760 Super Duplex Steel stud bolts**, which have been specially developed for deployment in highly corrosive, high-pressure environments. These stud bolts, which boast an extremely high strength along with excellent resistance to pitting, crevice corrosion, as well as stress corrosion cracking, are specifically developed to function under challenging industrial conditions. Yasin Fasteners provides S32760 stud bolts to industries such as offshore oil and gas, marine, chemical processing, and desalination with both standard and special sizes following international quality requirements.
Super Duplex Steel S32760 stud bolts consist of about 25–26% chromium, 6–8% nickel, 3.5–4% molybdenum, and nitrogen. This high-performance alloy provides excellent resistance against chloride-rich environments and severe chemicals. The duplex microstructure of S32760 offers extremely high mechanical strength, with tensile strength of between 800 and 860 MPa and yield strength of between 550 and 620 MPa—almost double that of conventional austenitic stainless steels. Such properties, combined with superior fatigue resistance and heat stability, make S32760 stud bolts the best choice for applications in structurally or corrosively challenging environments.
