  • Chromium (Cr): 18 – 20%
  • Nickel (Ni): 8 – 10.5%
  • Carbon (C): Max 0.08%
  • Manganese (Mn): Max 2%
  • Silicon (Si): Max 1%
  • Iron (Fe): Balance

    • Key Benefit: Excellent corrosion resistance and good weldability.

    2. SS 316 Round Bar – Chemical Composition

  • Chromium (Cr): 16 – 18%
  • Nickel (Ni): 10 – 14%
  • Molybdenum (Mo): 2 – 3%
  • Carbon (C): Max 0.08%
  • Iron (Fe): Balance

    • Key Benefit: Superior resistance to chlorides and marine environments.

    3. Duplex Stainless Steel Round Bar – Composition

  • Chromium: 22 – 25%
