Aditya Stainless stands out as a trusted manufacturer and supplier of Stainless Steel 348 Bolts right in Kolkata, India. They provide top-notch fastening solutions tailored for critical and high-temperature industrial applications. Stainless Steel 348 (UNS S34800) is a stabilized austenitic stainless steel that includes niobium (columbium), giving it remarkable resistance to intergranular corrosion and impressive strength at high temperatures. These bolts are perfect for environments that face prolonged heat and mechanical stress. Commonly found in aerospace, chemical processing, power generation, and nuclear sectors, SS 348 bolts guarantee dependable fastening with superior creep and stress rupture resistance.
Stainless Steel 348 Bolts are made up of 18–20% chromium, 8–11% nickel, and niobium (up to 10 times the carbon content) to prevent carbide precipitation. This unique blend results in a tensile strength of at least 515 MPa, a yield strength of at least 205 MPa, and a good elongation of around 40%. The inclusion of columbium makes these bolts particularly suitable for welded structures and high-temperature applications, where resistance to intergranular corrosion and oxidation is essential. The alloy retains excellent mechanical properties even at elevated temperatures, ensuring good formability, weldability, and long-lasting structural integrity in challenging industrial settings.
