Lecong Stainless stands out as a top manufacturer and supplier based in Da Nang, Vietnam, specializing in high-quality Stainless Steel 348H Sheets and Plates. These products are known for their impressive high-temperature strength, resistance to corrosion, and remarkable durability over time. Stainless Steel 348H is a robust austenitic stainless steel that’s stabilized with titanium, which helps prevent carbide precipitation during welding and ensures it retains excellent mechanical properties even at elevated temperatures. Each sheet and plate is meticulously crafted to meet international standards, making them perfect for use in power generation, chemical processing, and industrial equipment where reliable high-temperature performance is essential.
The composition of Stainless Steel 348H Sheets and Plates includes iron, chromium (17–19%), nickel (8–12%), titanium, manganese, silicon, and a carefully controlled amount of carbon to boost strength at higher temperatures. Their mechanical properties are impressive, featuring a tensile strength ranging from 515 to 750 MPa and a yield strength between 205 and 275 MPa, along with outstanding creep and oxidation resistance at temperatures reaching 650–700°C. The titanium stabilization not only ensures dimensional stability but also prevents intergranular corrosion and maintains toughness during extended heat exposure. This unique blend of characteristics makes Stainless Steel 348H Sheets and Plates ideal for demanding thermal and structural applications.
