Khaleed Stainless is a reputable manufacturer and supplier based in Riyadh, Saudi Arabia, specializing in high-quality Stainless Steel 309/309S Stud Bolts. These bolts are crafted for exceptional strength, durability, and outstanding resistance to high-temperature corrosion. They’re commonly found in industries like chemical, petrochemical, power generation, and heat treatment, where secure fastening in extreme conditions is a must. Built to meet international standards, these stud bolts promise a long service life, excellent thermal stability, and reliable performance in critical industrial settings.
The composition of Stainless Steel 309/309S Stud Bolts includes iron, chromium (22–24%), and nickel (12–15%), which together provide remarkable resistance to oxidation and scaling at high temperatures. The 309S grade features a lower carbon content, which helps minimize carbide precipitation and boosts weldability while still maintaining impressive strength at elevated temperatures. In terms of mechanics, these stud bolts deliver a tensile strength of around 515 MPa, a yield strength of 205 MPa, and good elongation, ensuring they can handle thermal and mechanical stress with toughness and durability.
