SS 304/304L Plates are the most versatile and widely used stainless steel plates in the global market. Belonging to the austenitic family, these plates are frequently dual-certified, combining the high strength of Grade 304 with the superior corrosion resistance and low-carbon properties of Grade 304L. The "L" designation signifies a lower carbon content (maximum 0.03%), which effectively eliminates carbide precipitation during the welding process. This makes the material exceptionally reliable for heavy-gauge components used in architectural, chemical, and food processing environments where structural integrity post-welding is critical.

Manufactured in accordance with ASTM A240 and ASME SA240 standards, our SS 304/304L plates offer an excellent balance of mechanical strength and high oxidation resistance at temperatures up to 870°C. These plates are available in various surface finishes, from the standard No. 1 Hot Rolled for industrial applications to 2B and Mirror finishes for aesthetic and hygienic purposes. Their non-magnetic nature in the annealed condition and remarkable ease of cleaning make them the primary choice for pharmaceutical equipment, kitchen appliances, and pressure vessel construction across the industrial landscape.



SS 304/304L Plates Features

  • » Dual Certification: Comprised of both 304 and 304L chemistry, providing the high mechanical strength of 304 with the extra-low carbon protection of 304L.
  • » Intergranular Corrosion Resistance: The low carbon content prevents chromium carbide precipitation during welding, ensuring the heat-affected zone remains corrosion-resistant without post-weld annealing.
  • » Excellent Formability: Can be easily brake-formed or deep-drawn into complex shapes, making it ideal for industrial sinks, hollowware, and architectural cladding.
  • » High Oxidation Resistance: Maintains structural integrity and resists scaling in intermittent service up to 870°C and continuous service up to 925°C.
  • » Hygienic & Non-Contaminating: The non-porous surface and ease of cleaning make it the global standard for food grade, beverage, and pharmaceutical manufacturing equipment.
  • » Cryogenic Toughness: Maintains excellent mechanical properties and high impact resistance even at extremely low temperatures, suitable for liquid gas storage applications.
  • » Aesthetic Versatility: Available in a wide spectrum of finishes, including 2B (smooth), No.4 (brushed), and No.8 (mirror), allowing for both functional and decorative use.
  • » Non-Magnetic Properties: As an austenitic grade, it is essentially non-magnetic in the annealed condition, which is vital for certain electronic and medical instrument housing.
