ASTM A240 Type 316Ti Stainless Steel Sheet & Plate
What is ASTM A240 Type 316Ti Stainless Steel Sheet and Plate?
As a professional stainless steel supplier, SHH STEEL is pleased to present ASTM A240 Type 316Ti Stainless Steel Sheet and Plate. Also known as UNS S31635 or SS316Ti, this titanium-stabilized version of Type 316 is designed to provide excellent resistance to intergranular corrosion after welding or continuous service in the sensitization temperature range (approximately 450–850°C).
The addition of titanium (minimum 5× carbon content, up to 0.70%) stabilizes carbon in the form of titanium carbides, preventing chromium carbide precipitation at grain boundaries. Combined with 2.00–3.00% molybdenum, Type 316Ti offers good resistance to pitting and crevice corrosion in chloride environments while maintaining excellent formability and weldability. SHH STEEL supplies ASTM A240 Type 316Ti in both sheet and plate forms, covering thicknesses from 0.5 mm to 100 mm, with widths up to 2500 mm and lengths up to 12000 mm. Custom sizes and surface finishes are available.
The material is typically delivered in the solution-annealed condition with full Mill Test Certificates (EN 10204 3.1). Whether for thin sheet fabrication or heavy plate applications, SHH STEEL provides consistent quality for chemical, petrochemical and high-temperature industrial projects worldwide.

Delivery Conditions
SHH STEEL supplies ASTM A240 Type 316Ti primarily in the solution-annealed and pickled condition. Detailed capabilities by surface finish are as follows:
2B Finish (Cold-rolled, annealed, pickled and skin-passed)
- Typical thickness range: 0.5 mm – 6.0 mm (most common 0.8 mm – 3.0 mm)
- Maximum width: up to 1500–2000 mm depending on thickness
- Preferred for applications requiring a smooth surface and good flatness.
No.1 Finish (Hot-rolled, annealed and pickled)
- Typical thickness range: 3.0 mm – 100 mm (most common 4.0 mm – 50 mm)
- Maximum width: up to 2000–2500 mm
- Standard finish for heavy plates used in chemical equipment, heat exchangers and high-temperature components.
Other Finishes
- BA (Bright Annealed): Available in thinner gauges
- HL (Hairline): Available on request
Protective PVC film can be applied on one or both sides. Precision cutting (plasma, laser or waterjet) and closer dimensional tolerances are available upon request.
Tolerances
Dimensional tolerances for ASTM A240 Type 316Ti sheet and plate follow ASTM A480/A480M.
- Thickness tolerances vary by product form and thickness. Cold-rolled sheet has tighter controls, while hot-rolled plate follows standard allowable deviations.
- Width tolerance is typically +6 mm / 0 mm.
- Length tolerance for cut-to-length material is normally +10 mm / 0 mm.
- Flatness is controlled according to ASTM A480; improved flatness can be supplied for precision fabrication.
- Edge conditions include mill edge, slit edge, sheared edge or plasma/laser cut edge according to customer preference.
Tighter tolerances can be arranged for special projects.
Weldability
ASTM A240 Type 316Ti offers good weldability using all common fusion welding processes, including GTAW (TIG), GMAW (MIG), SMAW and plasma welding. The titanium stabilization provides excellent resistance to intergranular corrosion in the heat-affected zone, even without post-weld annealing in many applications.
Matching or slightly over-alloyed filler metals such as ER316L or ER318 are commonly recommended. Preheating is generally not required. Proper cleaning and passivation after welding are recommended to restore full corrosion resistance, especially in chloride or chemical environments.

FAQ
- What is the main advantage of 316Ti compared with 316L?Type 316Ti is titanium-stabilized, providing excellent resistance to intergranular corrosion after continuous exposure to the sensitization temperature range (450–850°C). Type 316L relies on very low carbon content and is preferred for welded constructions that are not continuously exposed to these temperatures.
- What are the equivalent grades of ASTM A240 Type 316Ti?Common equivalents include UNS S31635, EN 1.4571 (X6CrNiMoTi17-12-2), JIS SUS316Ti and Chinese 06Cr17Ni12Mo2Ti.
- Is ASTM A240 Type 316Ti suitable for continuous high-temperature service?Yes. Due to titanium stabilization, it performs well in continuous service within the sensitization temperature range and offers better high-temperature stability than standard 316L in certain applications.
- What is the density of ASTM A240 Type 316Ti?Approximately 8.00 g/cm³.
- Can SHH STEEL supply dual-certified 316Ti material?Dual certification options can be evaluated based on specific chemistry and mechanical property requirements. Please contact us for confirmation.
