Lecong Stainless is a reputable manufacturer and supplier based in Da Nang, Vietnam, specializing in high-quality Stainless Steel 304H Sheets and Plates. These products are designed to perform exceptionally well in high-temperature and moderately corrosive environments. With a higher carbon content than the standard 304 grade, 304H offers improved creep strength and mechanical stability at elevated temperatures, making it perfect for applications that demand long-lasting durability. Lecong Stainless prides itself on precision manufacturing, outstanding surface finishes, and strict compliance with international standards. The Stainless Steel 304H Sheets and Plates are widely utilized in industries where strength, heat resistance, and corrosion protection are essential, delivering dependable solutions both locally and globally.
These sheets and plates consist of 18–20% chromium and 8–12% nickel, with a carbon content ranging from 0.04–0.10% to enhance high-temperature strength. Carefully controlled levels of manganese, silicon, and phosphorus boost toughness, workability, and mechanical stability. They boast a tensile strength of about 515 MPa, a yield strength of around 205 MPa, and an elongation of 40%. Their unique combination of creep resistance, oxidation resistance up to 1500°F (816°C), and excellent mechanical properties guarantees reliable performance in high-temperature and corrosive conditions.
