Stainless Steel 316Ti Welded Pipes Manufacturer in India
What is Stainless Steel 316Ti Welded Pipe?
Stainless Steel 316Ti Welded Pipe is a titanium-stabilized austenitic stainless steel pipe manufactured by forming stainless steel material into a tubular shape and joining the longitudinal seam through welding. It contains chromium, nickel and molybdenum, with titanium added to stabilize the grade for elevated-temperature service.
The titanium addition binds carbon and helps reduce chromium carbide precipitation during prolonged exposure to elevated temperatures. As a result, 316Ti can be considered for applications where resistance to intergranular corrosion and elevated-temperature service are important. Molybdenum also provides improved resistance to localized corrosion in chloride-containing environments.
Kamal Steels is a Stainless Steel 316Ti Welded Pipe Manufacturer and Exporter in India, based in Mumbai. The company supplies 316Ti welded pipes in different sizes, schedules, wall thicknesses, lengths and finishes for industrial and international requirements.
The commonly specified designation for pressure piping is ASTM A312 TP316Ti / ASME SA312 TP316Ti, with UNS designation S31635. Pipes can be supplied with testing, inspection and material certification according to applicable project requirements.

Stainless Steel 316Ti Welded Pipe Specifications
Stainless Steel 316Ti Welded Pipe is a titanium-stabilized austenitic stainless steel pipe containing chromium, nickel and molybdenum. Titanium is added to stabilize the carbon in the alloy and reduce the risk of sensitization during exposure to elevated temperatures. This makes 316Ti suitable for applications requiring corrosion resistance and reliable performance in elevated-temperature environments.
ASTM A312 TP316Ti is commonly specified for austenitic stainless steel pipe used in corrosive and high-temperature service. The molybdenum content provides improved resistance to pitting and crevice corrosion, while the titanium stabilization supports resistance to intergranular corrosion after exposure to elevated temperatures.

Stainless Steel 316Ti Welded Pipe Pressure Rating
The pressure rating of Stainless Steel 316Ti Welded Pipe depends on pipe size, wall thickness, operating temperature, allowable stress and the applicable piping design code. The actual pressure capacity should therefore be determined using the specific design conditions rather than a single generic pressure value.
| Factor | Effect on Pressure Design |
|---|---|
| Pipe Size | Outside diameter is considered in pressure design calculations. |
| Wall Thickness | Wall thickness directly affects pressure-carrying capacity. |
| Pipe Schedule | Higher schedules generally provide greater nominal wall thickness. |
| Operating Temperature | Allowable material stress varies with temperature. |
| Design Code | The applicable piping code determines the pressure design calculation. |
| Corrosion Allowance | Additional wall thickness may be required where applicable. |
The final allowable working pressure should be established using the actual design pressure, temperature, pipe dimensions, material properties and applicable engineering code.
Stainless Steel 316Ti Welded Pipe Equivalent Grades
Stainless Steel 316Ti is identified by different designations under international standards. These designations help manufacturers, engineers and procurement teams identify the titanium-stabilized 316 stainless steel grade.

|---|---|
| ASTM | 316Ti |
| ASME | SA312 TP316Ti |
| UNS | S31635 |
| EN | 1.4571 |
