SS 316/316L Plates are widely regarded as the "marine grade" of stainless steels, distinguished from standard 304 by the addition of 2-3% Molybdenum. This critical alloying element significantly enhances the material's resistance to pitting and crevice corrosion in chloride-rich environments, such as seawater or de-icing salt applications. Our plates are typically dual-certified, meeting the high-tensile requirements of Grade 316 while maintaining the low-carbon (0.03% max) profile of Grade 316L. This ensures that the plates are immune to sensitization and intergranular corrosion after welding, making them the preferred choice for heavy-duty structural components.

Manufactured to ASTM A240 and ASME SA240 standards, our SS 316/316L plates offer exceptional performance in the pharmaceutical, chemical processing, and food and beverage industries. Beyond their superior corrosion resistance, these plates exhibit higher creep strength and better mechanical properties at elevated temperatures than most austenitic steels. Whether used in high-purity medical environments or aggressive offshore platforms, these plates provide a reliable, long-lasting solution with excellent formability and surface stability, available in finishes ranging from industrial No. 1 to decorative Mirror (No. 8).



SS 316/ 316L Plates Features

  • » Superior Pitting Resistance: The addition of Molybdenum (2-3%) provides significantly better resistance to pitting and crevice corrosion in chloride-contaminated environments compared to Grade 304.
  • » Dual Grade Certification: Combines the high mechanical strength of 316 with the extra-low carbon content of 316L, offering protection against sensitization during welding.
  • » Marine Environment Stability: Known as "Marine Grade" stainless steel for its exceptional durability and corrosion resistance in salt-water and offshore applications.
  • » High-Temperature Creep Strength: Exhibits better mechanical properties and higher creep resistance at elevated temperatures, making it suitable for pressure vessels and heat exchangers.
  • » Excellent Weldability: Can be easily welded using all standard fusion methods; the 316L variant eliminates the need for post-weld annealing in heavy-gauge sections.
  • » Hygienic & Pharmaceutical Grade: Its resistance to chemical cleaners and non-reactive surface makes it the global standard for medical implants and sterile pharmaceutical production.
  • » Cryogenic Versatility: Maintains excellent toughness and structural integrity even at extreme sub-zero temperatures, suitable for liquid gas processing.
  • » Non-Magnetic Nature: Remains essentially non-magnetic in the annealed condition, which is critical for specialized electronic housing and sensitive medical imaging equipment.
