Lecong Stainless is a well-respected manufacturer and supplier based in Da Nang, Vietnam, known for its top-notch Stainless Steel 347 Fasteners. These fasteners are designed to offer exceptional durability, resist corrosion, and maintain strength even at high temperatures. Stainless Steel 347 is a titanium-stabilized austenitic stainless steel, specifically engineered to combat intergranular corrosion and ensure mechanical stability, even after welding or prolonged exposure to heat. Each fastener is precision-crafted to meet international quality standards, making them perfect for critical applications in sectors like power generation, petrochemical, chemical processing, and marine environments. With advanced manufacturing techniques, Lecong Stainless promises consistent performance and reliability.
The composition of Stainless Steel 347 Fasteners includes iron, chromium (17–19%), nickel (9–13%), titanium for stabilization, along with manganese, silicon, and a controlled amount of carbon. The addition of titanium helps prevent carbide precipitation during welding, boosting corrosion resistance and extending the fasteners’ service life. Their mechanical properties boast a tensile strength ranging from 515 to 750 MPa and a yield strength of 205 to 275 MPa, along with excellent resistance to oxidation and creep at temperatures reaching up to 700°C. The austenitic microstructure ensures toughness, dimensional stability, and long-lasting reliability, even in demanding conditions.
