chromium, 10.0–14.0% nickel, 2.00–3.00% molybdenum, and titanium stabilisation (5×C min,
0.70% max).
Mechanical Properties of Stainless Steel 316Ti Heat Exchanger Tubes
Verify the essential strength, hardness, and durability ratings of
the SS 316Ti heat exchanger tube materials.
It meet strict mechanical standards: 515 MPa minimum tensile and 205 MPa yield strength.
The 35% minimum elongation ensures these tubes remain durable and resistant to
stress-related failure during operation.

Industrial Applications of SS 316Ti Heat Exchanger Tubes
316Ti heat exchanger tubes serve 4 primary industries: chemical processing, oil and gas refining, power generation, and pharmaceutical/food manufacturing.
Chemical and Petrochemical Processing
316Ti tubes are used in heat transfer for sulphuric acid and chloride-bearing streams, as they prevent the sensitisation during repeated thermal cycling.
Oil and Gas Refining
Ideal for crude distillation columns and overhead condensers resisting naphthenic acid and hydrogen sulphide above 425°C.
Power Generation
These tubes are used in boiler feedwater heaters and steam condensers to resist chloride stress corrosion from cooling water.
Pharmaceutical and Food Processing
Bright-annealed or electropolished SS 316Ti tubes meet hygienic surface requirements. Sterile heat exchangers and CIP systems use them.
Grade Comparisons: 316Ti vs 316L, 321H, 304H
Stainless Steel 316Ti vs 316L Heat Exchanger Tubes
This table highlights the structural and thermal differences between SS 316Ti and SS 316L heat exchanger tubes, focusing on high-temperature stability.
Titanium stabilisation allows 316Ti to carry up to 0.08% carbon without the risks found in 316L. Since 316L (capped at 0.03% carbon) becomes sensitive at 425°C, engineers prefer 316Ti for high-temperature heat exchanger projects.
| Feature | SS 316Ti (UNS S31635) | SS 316L (UNS S31603) |
|---|---|---|
| Carbon Content | Max 0.08% | Max 0.03% |
| Stabilizing Element | Titanium (Ti) | None |
| Sensitization Risk | Low (Stable up to 815°C) | Higher above 425°C for long durations |
| Creep Strength | Higher at elevated temperatures | Lower at high temperatures |
| Primary Use Case | Sustained high-heat exchangers | Ambient temperature welded structures |
Stainless Steel 316Ti vs 321H for Heat Exchanger Tubes
This table compares SS 316Ti and SS 321H heat exchanger tubes, emphasising how molybdenum content affects corrosion resistance in thermal systems.
Titanium stabilises both classifications. However, 316Ti incorporates 2.00–3.00% molybdenum, while 321H employs an additional 0.04–0.10% carbon. These distinct chemical profiles cater to very different high-temperature application requirements. In chloride conditions, molybdenum makes 316Ti pitting and crevice corrosion resistant.
| Feature | SS 316Ti | SS 321H |
|---|---|---|
| Molybdenum (Mo) | 2.00% - 3.00% | Trace / None |
| Titanium (Ti) | 5×(C+N) min to 0.70% max | 4×(C+N) min to 0.70% max |
| Carbon (C) | Max 0.08% | 0.04% - 0.10% |
| Chloride Resistance | Excellent (Resists Pitting) | Moderate to Poor |
| Strength at Heat | Good | Superior (Highest Creep Resistance) |
Stainless Steel 316Ti vs 304H for Heat Exchanger Tubes
This table contrasts the performance of SS 316Ti against SS 304H to help buyers identify when a grade upgrade is technically necessary.
304H lacks both molybdenum and titanium. It’s a lower-cost option for non-chloride, moderate-temperature service. Select 316Ti whenever chloride exposure, sulphuric acid, or sustained temperatures above 425°C are present.
| Feature | SS 316Ti | SS 304H |
|---|---|---|
| Alloying Matrix | Cr-Ni-Mo + Titanium | Cr-Ni (18/8) + High Carbon |
| Acid Resistance | High (Sulphuric/Acetic acids) | Moderate |
| Chloride Pitting | Resistant (PREN ~24) | Sensitive (PREN ~19) |
| Max Service Temp | Up to 850°C | Up to 800°C (Oxidising) |
| Cost Profile | Premium Performance | Economical / Standard |
