Uday Flanges is a prominent manufacturer and supplier of Stainless Steel 348 flanges, headquartered in Dubai, UAE. Eminent for providing premium quality and precision-flanges, Uday Flanges serves different industries needing high-temperature and corrosion-resistant products. Stainless Steel 348 flanges are highly appreciated for excellent intergranular corrosion stability and superior performance in high-temperature conditions. With emphasis on quality, timely delivery, and adherence to global standards, Uday Flanges caters to clients in industries like chemical processing, aerospace, oil and gas, and power generation, becoming the first choice partner in the industrial flanges business.
Stainless Steel 348 flanges consist predominantly of chromium (17–20%) and nickel (8–11%) with columbium (niobium) added to improve stability towards carbide precipitation. This inclusion enhances high temperature performance and intergranular corrosion resistance, even following welding. From a mechanical perspective, these flanges are subject to a tensile strength of about 550 MPa and a yield strength of about 240 MPa. They also have good ductility, oxidation resistance, as well as creep strength at high temperatures. Chemical stability and mechanical toughness of Stainless Steel 348 render it suitable for thermal cycling and ongoing continuous high heat exposure applications.
