Vishal Flanges is a reputable manufacturer and supplier of Stainless Steel 348 Flanges, based in Delhi, India. They specialize in providing top-notch flanges that can withstand the rigors of demanding industrial settings. Stainless Steel 348 is a niobium-stabilized austenitic stainless steel, crafted to deliver outstanding resistance to intergranular corrosion and perform well under high temperatures. Vishal Flanges offers a diverse range of flanges, including weld neck, slip-on, blind, threaded, and socket weld, all made in accordance with international standards like ASME, ASTM, and DIN. These flanges are perfect for industries such as aerospace, chemical processing, power generation, and petrochemicals, where durability, stability, and resistance to corrosion are essential.
The composition of Stainless Steel 348 Flanges includes 17–20% chromium and 8–11% nickel, with niobium (columbium) added to prevent carbide precipitation. This unique blend ensures that the flanges resist intergranular corrosion, even after welding and prolonged exposure to high temperatures. They boast a tensile strength of about 515 MPa and a yield strength of 205 MPa, providing solid mechanical stability when exposed to heat. Additionally, Stainless Steel 348 excels in creep strength and oxidation resistance, making it an excellent choice for high-stress environments that demand long-lasting performance and structural integrity.
