Emilio Stainless, located in Manila, Philippines, is a reputable manufacturer and supplier of top-notch Stainless Steel 309 / 309S Stud Bolts. Designed to withstand high temperatures and tough industrial conditions, these stud bolts boast impressive corrosion resistance, mechanical strength, and durability. The 309/309S grades are known for their exceptional oxidation resistance and long-lasting performance in heat-heavy environments. At Emilio Stainless, each stud bolt is crafted with care and goes through rigorous quality checks to ensure they meet international standards. These bolts deliver secure, dependable, and high-strength fastening solutions, making them perfect for chemical, petrochemical, power generation, and industrial piping systems.
Stainless Steel 309 / 309S Stud Bolts are made up of 22–24% chromium, 12–15% nickel, and a carbon content of up to 0.12% for 309 and ≤0.08% for 309S, along with small amounts of manganese, silicon, and phosphorus. They showcase a tensile strength of 520–620 MPa (for 309) and 550–620 MPa (for 309S), with a yield strength of about 210–250 MPa. These bolts are known for their excellent toughness, ductility, and dimensional stability, even at high temperatures. The low-carbon 309S variant enhances weldability and minimizes carbide precipitation, making them ideal for long-term, high-temperature industrial use.
