Our Stainless Steel 309/309S Stud Bolts are crafted from an austenitic stainless steel alloy that contains around 22–24% chromium and 12–15% nickel. The 309S variant features a lower carbon content, which improves weldability and minimizes the risk of carbide precipitation during exposure to high temperatures. Both grades boast remarkable oxidation resistance up to 1038°C (1900°F) and maintain solid mechanical strength even in elevated temperature conditions. Additionally, these stud bolts are resistant to corrosion in mildly aggressive environments and perform reliably under thermal stress.
You’ll find Stainless Steel 309/309S Stud Bolts commonly used in high-temperature structural applications like heat exchangers, furnace fixtures, boilers, kilns, and incinerators. Their ability to maintain strength and resist scaling at high temperatures makes them a preferred choice for environments that experience frequent heating and cooling cycles. These stud bolts ensure secure fastening in critical equipment and promise long-lasting performance in demanding industrial operations. With a perfect blend of strength, heat resistance, and corrosion protection, 309/309S stud bolts are vital components in thermal and chemical processing systems.
