Kyaw Stainless, a prominent manufacturer and supplier located in Naypyidaw, Myanmar, specializes in top-notch Stainless Steel 304L Flanges that are crafted for outstanding corrosion resistance, strength, and weldability. These flanges are produced using cutting-edge technology and high-quality raw materials, ensuring they are durable, precisely made, and perform exceptionally well in a variety of operating conditions. The Stainless Steel 304L, a low-carbon version of 304, offers improved resistance to intergranular corrosion, especially after welding or exposure to heat. Kyaw Stainless provides dependable and cost-effective flange solutions that adhere to international standards, catering to industries like chemical processing, food and beverage, petrochemical, and power generation.
Stainless Steel 304L Flanges consist of chromium (18–20%), nickel (8–12%), and carbon (≤0.03%), along with manganese (≤2%), silicon (≤1%), phosphorus (≤0.045%), and sulfur (≤0.03%). The low carbon content helps reduce carbide precipitation during welding, enhancing corrosion resistance. In terms of mechanical properties, these flanges boast a tensile strength of around 485 MPa, a yield strength of 170 MPa, and an elongation of 40%. They also maintain excellent formability, ductility, and toughness, even at cryogenic temperatures, making them suitable for both low and high-temperature applications.
