AISI 316Ti Stainless Steel Plate | 316Ti China steel mill-Direct Supply
What is AISI 316Ti Stainless Steel?
As a professional China steel mill-Direct Supply and stainless steel plate supplier, SHH STEEL is pleased to present AISI 316Ti Stainless Steel Plate.
AISI 316Ti (UNS S31635) is a titanium-stabilized version of the molybdenum-bearing austenitic stainless steel 316. It contains approximately 16–18% chromium, 10–14% nickel and 2–3% molybdenum, with intentional titanium addition to stabilize the grade against intergranular corrosion. Titanium combines preferentially with carbon to form stable titanium carbides, preventing chromium carbide precipitation at grain boundaries during welding or exposure to the sensitization temperature range.
This stabilization allows AISI 316Ti to maintain good corrosion resistance after welding and in service at elevated temperatures, while retaining the improved pitting and crevice corrosion resistance provided by molybdenum. The grade is non-magnetic in the annealed condition and is widely used in chemical processing, heat exchangers, exhaust systems and other applications requiring both chloride resistance and high-temperature welded performance.
SHH STEEL supplies AISI 316Ti as true China steel mill-Direct Supply, sourcing directly from major Chinese stainless steel mills. This model delivers competitive mill pricing, consistent quality, complete heat traceability and reliable delivery. SHH STEEL offers AISI 316Ti in plate and sheet form across a practical range of thicknesses and surface finishes.
AISI 316Ti is frequently compared with a240 316, a240 316l, a240 316h, a240 321, a240 304l and a240 317l when selecting stabilized or molybdenum-bearing grades. SHH STEEL provides technical support to help customers choose the most appropriate material.

Chemical Composition
Typical Chemical Composition of AISI 316Ti (UNS S31635):
| Element | Content (%) |
|---|---|
| Carbon (C) | ≤ 0.08 |
| Silicon (Si) | ≤ 1.00 |
| Manganese (Mn) | ≤ 2.00 |
| Phosphorus (P) | ≤ 0.045 |
| Sulfur (S) | ≤ 0.030 |
| Chromium (Cr) | 16.00 – 18.00 |
| Nickel (Ni) | 10.00 – 14.00 |
| Molybdenum (Mo) | 2.00 – 3.00 |
| Titanium (Ti) | 5 × (C + N) min – 0.70 max |
| Nitrogen (N) | ≤ 0.10 |
| Iron (Fe) | Balance |
The intentional titanium addition is the key stabilizing element in AISI 316Ti. Titanium combines with carbon and nitrogen to form stable titanium carbides/nitrides, preventing chromium depletion at grain boundaries. Combined with molybdenum (2–3%), the grade delivers both improved pitting resistance and excellent resistance to intergranular corrosion after welding or high-temperature exposure. SHH STEEL carefully controls the titanium-to-carbon ratio to ensure effective stabilization.
Mechanical Properties
Annealed Condition (typical values)
| Property | Value |
|---|---|
| Tensile Strength | ≥ 515 MPa (75 ksi) |
| Yield Strength (0.2%) | ≥ 205 MPa (30 ksi) |
| Elongation (in 50 mm) | ≥ 40% |
| Hardness | ≤ 217 HB |
AISI 316Ti offers mechanical properties similar to standard 316, with good strength, excellent ductility and toughness. The titanium stabilization does not significantly affect room-temperature mechanical properties but provides important benefits after welding and in elevated-temperature service. SHH STEEL supplies material with consistent mechanical properties suitable for fabrication and welding.
Physical Properties Density is approximately 8.00 g/cm³. The grade is non-magnetic in the annealed condition. Melting range is approximately 1370–1400°C.
Material Comparison
| Grade | Stabilization | Mo (%) | Pitting Resistance | Weldability & IGC | High-Temp Suitability | Typical Preference |
|---|---|---|---|---|---|---|
| AISI 316 | None | 2.0–3.0 | Better | Good | Moderate | General chloride service |
| AISI 316L | Low carbon | 2.0–3.0 | Better | Excellent | Moderate | Welded chloride service |
| AISI 316Ti | Titanium | 2.0–3.0 | Better | Excellent | Better | Stabilized high-temp chloride service |
| AISI 316H | Higher carbon | 2.0–3.0 | Better | Moderate | Higher strength | High-temp strength under load |
| AISI 321 | Titanium | — | Good | Excellent | Good | Stabilized non-Mo high-temp service |
| AISI 317L | Low carbon | 3.0–4.0 | Superior | Excellent | Moderate | More severe chloride environments |
AISI 316Ti is selected when both improved pitting resistance (from molybdenum) and stabilization against intergranular corrosion (from titanium) are required, particularly for welded constructions that will operate at elevated temperatures. Compared with a240 316l, it offers better performance in continuous high-temperature service. Compared with a240 321, it provides superior pitting resistance due to molybdenum. For higher molybdenum content, SHH STEEL recommends a240 317l.
Corrosion Resistance
AISI 316Ti offers excellent resistance to atmospheric corrosion, fresh water, food products and many chemical environments. The molybdenum addition provides superior resistance to pitting and crevice corrosion in chloride-containing media compared with 304/321, while the titanium stabilization ensures excellent resistance to intergranular corrosion after welding or exposure to the sensitization temperature range.
It performs well in chemical processing, heat exchangers and applications involving moderate chlorides at elevated temperatures. In highly concentrated chlorides or very aggressive environments, pitting or stress corrosion cracking can still occur. For more severe chloride service, SHH STEEL recommends a240 317l or a240 2205.
Weldability
AISI 316Ti has excellent weldability due to titanium stabilization. Matching or appropriate titanium-stabilized / 316-type filler metals are recommended. The stabilization effectively prevents intergranular corrosion in the heat-affected zone, making post-weld annealing generally unnecessary for most applications.
SHH STEEL recommends proper welding procedures and post-weld cleaning to achieve optimum corrosion performance. This combination of molybdenum-enhanced pitting resistance and titanium stabilization is the main advantage of AISI 316Ti for welded high-temperature service in chloride environments.
Heat Treatment
AISI 316Ti is normally supplied in the solution-annealed condition by SHH STEEL.
Recommended solution annealing temperature range is 1010–1120°C, followed by rapid cooling. Proper annealing ensures that titanium is available for effective stabilization and optimizes both room-temperature ductility and corrosion resistance. SHH STEEL controls heat treatment to ensure consistent quality.
