The Stainless Steel 309 and 309S stud bolts are primarily alloyed with chromium (about 23%) and nickel (roughly 13%), which gives them outstanding oxidation and corrosion resistance. The 309S variant features lower carbon content, enhancing its weldability and reducing carbide precipitation. Mechanically, these bolts boast high tensile strength (around 75 ksi) and good toughness at elevated temperatures, making them perfect for tough environments. Their remarkable resistance to scaling and oxidation up to 1100°C guarantees durability in high-heat applications. Ed Stainless produces these bolts in accordance with ASTM A193 standards, ensuring reliable mechanical performance for industrial use.
