316 Stainless Steel Chemical Composition & Mechanical Properties

1. Why is chromium added to 316 stainless steel? Chromium (16-18%) forms a protective oxide layer, enhancing oxidation and general corrosion resistance.

2. What is the yield strength of 316 at room temperature? ≥205 MPa in the annealed condition.

3. Does 316 contain nitrogen? It may contain up to 0.10% nitrogen to stabilize the austenitic structure and improve strength.

4. How does molybdenum improve 316's performance? Molybdenum reduces the risk of pitting corrosion in chloride-rich environments.

5. What is the hardness of 316 stainless steel? Brinell hardness ≤201 HB in the annealed state.
