Yasin Fasteners of Istanbul, Turkey, is a reliable producer and supplier of stainless steel 347 stud bolts that have wonderful resistance to intergranular corrosion and are highly resistant in high-temperature applications. These stud bolts are produced from niobium-stabilized austenitic stainless steel, which is the best for welded structures as well as those involving repeated thermal cycling. Yasin Fasteners provides stainless steel 347 stud bolts of different specifications and sizes for aerospace, chemical processing, power generation, and thermal equipment manufacturing industries. All of these products are manufactured based on international quality standards.
Stainless steel 347 stud bolts comprise about 17–19% chromium, 9–13% nickel, and niobium, which stabilizes the alloy against chromium carbide precipitation upon welding or high-temperature exposure. Such stabilization improves resistance to intergranular corrosion and offers superior mechanical strength and oxidation resistance up to 870°C (1600°F). The bolts retain adequate creep resistance and endurance under thermal stress.
