Chemical Composition
316Ti combines titanium stabilization with molybdenum alloying for corrosion-oriented service. It is useful for process and flue-gas components, but is not a general replacement for the hottest furnace-liner grades.

Mechanical Properties
Stabilization addresses sensitization; it is not a mechanical-strength or maximum-temperature rating. For sustained load, compare creep data for the ordered condition.

| Property | Value | Unit |
|---|---|---|
| 0.2% proof strength, Rp0.2 | ≥240 | MPa |
| 1.0% proof strength, Rp1.0 | ≥270 | MPa |
| Tensile strength, Rm | 540–690 | MPa |
| Elongation after fracture | ≥40 | % |

Physical Properties
Account for austenitic thermal expansion in welded assemblies. Weight estimates need a density matched to the ordered grade and condition.

| Density at 20°C | 8.0 | kg/dm³ |
| Modulus of elasticity at 20°C | 200 | GPa |
| Thermal expansion, 20–100°C | 16.5 | 10⁻⁶/K |
| Thermal conductivity at 20°C | 15 | W/m·K |
| Specific heat capacity at 20°C | 500 | J/kg·K |
| Electrical resistivity at 20°C | 0.75 | µΩ·m |

High-Temperature Characteristics
Ti or Nb stabilization helps address sensitization in welded or elevated-temperature service. Gas chemistry, corrosion and load still determine suitability.

Available Dimensions
We quote dimensions and tolerances for your selected form and quantity; there is no single stock-size range covering every grade and form.
Processing & Welding
Share the drawing, delivery condition, forming method, joint design, filler requirements, WPS/PQR, heat input, cleaning or passivation and NDT scope. Drawing geometry and the ordered standard help the fabricator prepare the process plan and qualified procedure.
Processing & WeldingIndustry Applications
Consider welded process equipment, hot piping and heat-exchanger components where sensitization and corrosion must be assessed together.
Inspection Options
- MTC identifying the heat, grade, ordered standard and reported test results.
- Dimensional, surface, traceability and marking records specified by the purchase order.
- NDT, PMI, third-party inspection or additional test reports only when ordered.
- EN 10204 3.1 wording only when the issued certificate explicitly carries that type.
