What is 316 Stainless Steel Round Bar?
316 Stainless Steel Round Bar is an austenitic chromium-nickel stainless steel with added molybdenum, which enhances its resistance to corrosion, especially in chloride-rich environments. It is commonly used in applications where exposure to chemicals, saltwater, or extreme temperatures is a concern.
Chemical Composition of 316 SS
- Chromium (Cr): 16–18%
- Nickel (Ni): 10–14%
- Molybdenum (Mo): 2–3%
- Carbon (C): Max 0.08%
- Manganese (Mn): Max 2%
- Silicon (Si): Max 1%
- Iron (Fe): Balance
The addition of molybdenum significantly improves resistance to pitting and crevice corrosion.
