Lecong Stainless is a reputable manufacturer and supplier based in Da Nang, Vietnam, known for its top-notch Stainless Steel 348 Bolts. These bolts are designed to deliver outstanding strength, resist corrosion, and endure high temperatures, making them perfect for demanding applications. Stainless Steel 348 is a titanium-stabilized austenitic stainless steel that effectively combats intergranular corrosion while maintaining its mechanical integrity, even when exposed to elevated temperatures for extended periods. Each bolt is precision-engineered to meet international standards, ensuring they are reliable for critical fastening tasks in sectors like power generation, chemical processing, and industrial equipment. Lecong Stainless is committed to maintaining consistent quality through advanced production techniques and rigorous quality control measures.
The composition of Stainless Steel 348 Bolts primarily 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 bolts 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 toughness and elongation, ensuring they perform reliably under pressure. Their austenitic structure contributes to dimensional stability, heat resistance, and long-lasting durability in challenging thermal and chemical environments.
