Lecong Stainless stands out as a top manufacturer and supplier based in Da Nang, Vietnam, specializing in high-quality Stainless Steel 348H Pipe Fittings. These fittings are designed to offer exceptional durability, resistance to corrosion, and reliable performance even at high temperatures. Made from titanium-stabilized austenitic stainless steel, Stainless Steel 348H is specifically crafted to avoid intergranular corrosion while maintaining its mechanical strength, even when exposed to elevated temperatures for extended periods. Each fitting is precision-engineered to meet international standards, making them perfect for critical piping systems in sectors like power generation, chemical processing, and industrial equipment. Lecong Stainless is committed to delivering consistent quality through advanced production techniques and rigorous quality control.
The composition of Stainless Steel 348H Pipe Fittings 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, which boosts corrosion resistance and preserves strength at high temperatures. These fittings boast impressive mechanical properties, including a tensile strength ranging from 515 to 750 MPa, yield strength between 205 and 275 MPa, and outstanding resistance to creep and oxidation at temperatures reaching 650–700°C. The austenitic structure contributes to their toughness, dimensional stability, and long-lasting reliability in challenging thermal and chemical environments.
