Stainless Steel 316 Round Bars

What is Stainless Steel 316Ti Round Bar?

Stainless Steel 316Ti is a titanium-stabilized version of 316 stainless steel. It belongs to the austenitic stainless steel family and contains molybdenum for improved corrosion resistance, particularly against chlorides. The addition of titanium helps stabilize the structure against chromium carbide precipitation, making it more resistant to intergranular corrosion, especially after welding or prolonged exposure to high temperatures.

Stainless Steel 316Ti Round Bars are solid cylindrical bars used for machining components, shafts, fasteners, marine fittings, pump parts, and structural components exposed to corrosive and high-temperature environments.

The key advantage of Stainless Steel 316Ti over standard 316 is its enhanced resistance to sensitization and improved high-temperature performance.


Key Features of Stainless Steel 316Ti Round Bars

  • Excellent resistance to pitting and crevice corrosion
  • Superior resistance to chloride environments
  • Titanium stabilization prevents intergranular corrosion
  • High strength at elevated temperatures
  • Good weldability
  • Excellent formability and fabrication properties
  • Non-magnetic in annealed condition
  • Long service life in aggressive industrial environments

Chemical Composition of Stainless Steel 316Ti Round Bars (%)

  • Chromium (Cr): 16.00 – 18.00
  • Nickel (Ni): 10.00 – 14.00
  • Molybdenum (Mo): 2.00 – 3.00
  • Titanium (Ti): 5xC min to 0.70 max
  • Carbon (C): ≤ 0.08
  • Manganese (Mn): ≤ 2.00
  • Silicon (Si): ≤ 1.00
  • Phosphorus (P): ≤ 0.045
  • Sulfur (S): ≤ 0.030
  • Iron (Fe): Balance

Role of Major Alloying Elements

  • Chromium: Enhances corrosion resistance.
  • Nickel: Improves toughness and ductility.
  • Molybdenum: Increases resistance to pitting in chloride environments.
  • Titanium: Stabilizes the structure, preventing carbide precipitation during welding.

Mechanical Properties of Stainless Steel 316Ti Round Bars

In annealed condition, Stainless Steel 316Ti typically offers:

  • Tensile Strength: ≥ 515 MPa
  • Yield Strength (0.2% Offset): ≥ 205 MPa
  • Elongation: ≥ 40%
  • Hardness: ≤ 95 HRB
  • Impact Strength: Excellent at room temperature

The mechanical properties remain stable even at moderately elevated temperatures, making Stainless Steel 316Ti suitable for heat exchangers and pressure vessels.


Physical Properties of Stainless Steel 316Ti

  • Density: 8.00 g/cm³
  • Melting Range: 1370 – 1400°C
  • Modulus of Elasticity: 193 GPa
  • Thermal Conductivity: 16.3 W/m·K
  • Electrical Resistivity: 740 nΩ·m
  • Specific Heat Capacity: 500 J/kg·K

Corrosion Resistance of Stainless Steel 316Ti Round Bars

Stainless Steel 316Ti provides excellent resistance to:

  • Marine environments
  • Chloride-rich conditions
  • Chemical processing environments
  • Acidic media (mild sulfuric and phosphoric acids)
  • Resistance to pitting and crevice corrosion

The addition of molybdenum significantly enhances resistance to localized corrosion. Titanium stabilization ensures protection against intergranular corrosion after welding.

Because of these properties, Stainless Steel 316Ti is widely used in offshore platforms, desalination plants, chemical tanks, and marine hardware.


High-Temperature Performance

Stainless Steel 316Ti performs better than standard 316 in high-temperature applications.

  • Suitable for continuous service up to 600–800°C
  • Resistant to sensitization
  • Good creep resistance
  • Maintains strength in prolonged heating conditions

It is particularly useful in exhaust manifolds, furnace parts, and high-temperature process equipment.


Heat Treatment of Stainless Steel 316Ti

Stainless Steel 316Ti cannot be hardened by heat treatment.

Solution Annealing:

Heat at 1040°C – 1100°C followed by rapid cooling.Cold working can increase strength and hardness.

The titanium addition ensures structural stability even after exposure to welding temperatures.


Machinability of Stainless Steel 316Ti Round Bars

Stainless Steel 316Ti has moderate machinability due to its austenitic structure.

Machining Recommendations:

  • Use sharp carbide tooling
  • Maintain slower cutting speeds
  • Apply sufficient coolant
  • Avoid interruptions to reduce work hardening

Despite moderate machinability, it produces strong and durable precision components.


Weldability of Stainless Steel 316Ti

Stainless Steel 316Ti has excellent weldability using:

  • TIG (GTAW)
  • MIG (GMAW)
  • Shielded Metal Arc Welding (SMAW)

The titanium stabilization prevents carbide precipitation, reducing the risk of weld decay.Post-weld heat treatment is usually not required unless specified for critical applications.
