Lecong Stainless stands out as a top manufacturer and supplier based in Da Nang, Vietnam, specializing in high-quality Stainless Steel 347H Pipe Fittings. These fittings are designed to offer exceptional corrosion resistance, impressive strength at high temperatures, and long-lasting durability. Made from titanium-stabilized austenitic stainless steel, Stainless Steel 347H is specifically crafted to avoid intergranular corrosion and to maintain its mechanical integrity even when exposed to high 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 various industrial applications. Lecong Stainless is committed to delivering consistent quality through advanced manufacturing techniques and rigorous quality control measures.
The composition of Stainless Steel 347H 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 mechanical strength at elevated temperatures. These fittings boast impressive mechanical properties, including a tensile strength ranging from 515 to 750 MPa and a yield strength between 205 and 275 MPa, along with excellent resistance to creep and oxidation at temperatures reaching up to 700°C. The austenitic structure ensures toughness, dimensional stability, and reliable performance in challenging thermal and chemical environments.
