Stainless Steel Sheet (Grade 304/304L)

The Stainless Steel Sheet (Grade 304/304L) is one of the most widely used stainless steel products across multiple industries due to its excellent corrosion resistance, superior strength, outstanding formability, and exceptional weldability. As an austenitic stainless steel, 304/304L stainless steel sheet delivers long-term performance in diverse environments ranging from food processing to chemical processing and architectural applications.

The 304L variant has a lower carbon content (≤ 0.03%), making it ideal for welded structures where intergranular corrosion resistance is critical after welding.


Key Feature

  • Excellent Corrosion Resistance
    Resists corrosion from most acids, moisture, and atmospheric conditions.

  • Superior Weldability
    304L’s low carbon content prevents carbide precipitation during welding, minimizing corrosion risk at welded joints.

  • High Strength & Durability
    Delivers excellent tensile strength for structural and mechanical applications.

  • Outstanding Formability
    Easily cut, bent, drawn, or stamped into complex shapes for custom fabrication.

  • Sanitary Surface Finish
    Ideal for food, pharmaceutical, and medical applications due to its hygienic, non-reactive properties.

  • Wide Range of Finishes & Thicknesses
    Customizable surface finishes for both industrial and decorative uses.
