2. Material Composition (Typical for 316Ti Stainless Steel)
| Element | Content (%) |
|---|---|
| Carbon (C) | ≤ 0.08 |
| Chromium (Cr) | 16.0 – 18.0 |
| Nickel (Ni) | 10.0 – 14.0 |
| Molybdenum (Mo) | 2.0 – 3.0 |
| Titanium (Ti) | 5 × C – 0.7 |
| Manganese (Mn) | ≤ 2.0 |
| Silicon (Si) | ≤ 1.0 |
| Iron (Fe) | Balance |
316Ti stainless steel is a titanium-stabilized grade offering excellent intergranular corrosion resistance and high-temperature strength, making it ideal for heat exchanger and power plant applications.
3. Mechanical Properties (316Ti)
