SS316Ti is SS316 with a little titanium added. The titanium ties up carbon so the steel keeps its corrosion resistance after welding and during long service at about 500–800 °C. It is common in European specifications, chemical plant, heat exchangers and exhaust systems; in many uses 316L does the same job.

SS316Ti or SS316L?
| SS316Ti | SS316L | |
|---|---|---|
| How weld decay is avoided | Titanium ties up carbon | Very low carbon |
| Long service at 500–800 °C | Better | Can sensitise over time |
| Polishing to a mirror | Harder | Easy |
| Availability in India | Less common | Very common |

Questions
- Can 316L replace 316Ti?
- Usually yes for welded parts below about 400 °C. For long service at higher temperatures, 316Ti is safer.
- Why is 316Ti common in German drawings?
- 1.4571 is a traditional standard grade in Europe, so many drawings call for it.
- Is 316Ti magnetic?
- No, it is austenitic and non-magnetic when annealed.
