Our products are designed to provide durability, corrosion resistance, and long-lasting reliability even under extreme heat and pressure.
Stainless Steel 304H Sheets and Plates are austenitic stainless steels that contain approximately 18–20% chromium and 8–11% nickel, along with a higher carbon content (0.04–0.10%) compared to standard 304. This unique composition enhances their strength at high temperatures and improves creep resistance. They boast excellent oxidation resistance and solid mechanical properties, with tensile strength ranging from 515 to 740 MPa and yield strength around 205 MPa. These plates maintain their structural integrity even in elevated temperatures, making them ideal for pressure vessels and heat exchangers.
