A small percentage of titanium adds a lot of quality to your alloy. Titanium stabilizes the alloy at extremely high temperatures of 800 degrees and above, which can occur during a chimney fire. Titanium combines with carbon, preventing the precipitation of chromium carbide from the material. If this precipitation would occur it leaves the alloy grain boundaries chromium depleted and susceptible to intergranular attack (corrosion). The main advantage of 316Ti is that alloy can be held at higher temperatures longer before sensitization occurs than in a non-stabilized alloy like 316L.
