Lecong Stainless is a well-respected manufacturer and supplier based in Da Nang, Vietnam, known for its top-notch Stainless Steel 348 Flanges that are built to endure high temperatures and harsh environments. These flanges are crafted with precision to guarantee outstanding durability, thermal stability, and resistance to intergranular corrosion. Thanks to cutting-edge production methods and rigorous quality control, Lecong Stainless delivers products that align with international standards. Stainless Steel 348 Flanges are celebrated for their exceptional creep strength and resistance to scaling, making them a dependable option for industries that require long-lasting and efficient flange solutions, both in Vietnam and around the globe.
These flanges are made up of chromium (17–19%) and nickel (9–13%), with columbium (niobium) added to prevent carbide precipitation during high-temperature use. They also include controlled levels of carbon, manganese, and silicon to enhance strength and toughness. With a tensile strength of about 515 MPa, a yield strength of around 205 MPa, and an elongation of 40%, these flanges boast excellent oxidation resistance up to 1500°F (816°C), ensuring they remain durable even in extreme heat. Their high creep resistance, toughness, and structural stability make Stainless Steel 348 Flanges highly effective in demanding and high-stress industrial applications.
