Stainless Steel 304/304L Sheets and Plates are austenitic alloys containing chromium and nickel, offering excellent corrosion resistance and toughness. The low carbon content of 304L reduces the risk of carbide precipitation during welding, improving weldability and corrosion performance. These grades provide good tensile strength, ductility, and impact resistance across a wide temperature range. Stainless Steel 304/304L maintains mechanical stability under stress, making it suitable for fabrication, forming, and welded applications requiring reliable performance and durability.
