Lecong Stainless stands out as a top manufacturer and supplier based in Da Nang, Vietnam, specializing in high-quality Stainless Steel 348 Pipes. These pipes are known for their remarkable high-temperature strength, corrosion resistance, and overall durability. Made from titanium-stabilized austenitic stainless steel, Stainless Steel 348 is specifically engineered to combat intergranular corrosion and maintain its mechanical integrity even when exposed to high temperatures for extended periods. Each pipe is meticulously crafted to adhere to international standards, making them perfect for critical applications in power generation, chemical processing, and various industrial equipment. Lecong Stainless is committed to delivering consistent quality through advanced production methods and rigorous quality checks.
The composition of Stainless Steel 348 Pipes includes iron, chromium (17–19%), nickel (8–12%), and titanium for stabilization, along with manganese, silicon, and a controlled amount of carbon. The titanium stabilization helps prevent carbide precipitation during welding, enhancing corrosion resistance and preserving strength at elevated temperatures. These pipes boast impressive mechanical properties, featuring a tensile strength ranging from 515 to 750 MPa, yield strength between 205 and 275 MPa, and outstanding creep and oxidation resistance at temperatures reaching 650–700°C. Their austenitic structure guarantees toughness, dimensional stability, and long-lasting reliability in challenging thermal and chemical conditions.
