Chemical Composition
The main chemical composition of TP316 stainless steel is as follows:
| Element |
Content |
| Carbon (C) |
≤0.08% |
| Manganese (Mn) |
≤2.00% |
| Phosphorus (P) |
≤0.045% |
| Sulfur (S) |
≤0.030% |
| Silicon (Si) |
≤1.00% |
| Nickel (Ni) |
10.0 - 14.0% |
| Chromium (Cr) |
16.0 - 18.0% |
| Molybdenum (Mo) |
2.0 - 3.0% |
The addition of molybdenum (Mo) enhances the corrosion resistance of the steel, especially in chloride - containing environments, making it highly resistant to pitting, crevice corrosion, and stress - corrosion cracking.
