Aditya Stainless stands out as a top-notch manufacturer and supplier of Stainless Steel 304L Flanges, celebrated for their remarkable corrosion resistance, durability, and outstanding weldability. Based in Kolkata, India, our SS 304L flanges find their way into a variety of industries, including oil & gas, chemical processing, pharmaceuticals, and food & beverage. The low-carbon nature of SS 304L helps to prevent carbide precipitation during welding, making it a perfect choice for applications sensitive to corrosion. We provide a wide array of flanges, such as weld neck, slip-on, blind, socket weld, and lap joint, all adhering to ASTM A182 and ASME B16.5 standards.
Stainless Steel 304L Flanges are made up of 18–20% chromium, 8–12% nickel, and a maximum of 0.03% carbon, along with small amounts of manganese, silicon, and phosphorus. This unique blend boosts corrosion resistance while minimizing the risk of intergranular attack post-welding. Typically, they boast a tensile strength of about 485 MPa, a yield strength of 170 MPa, and an elongation of 35–40%. SS 304L flanges are designed to maintain excellent mechanical integrity across various environments, including moderate chemical, acidic, and saline conditions, ensuring a long-lasting and dependable service life.
