316L stainless steel is more resistant to corrosion than 316 stainless steel. There may be no difference in everyday applications. However, because of its weldability, 316L is regarded as the superior corrosion resistance option. 316Ti is essentially 316 with some titanium (Ti) added to reduce the risk of corrosion resistance loss in the heat-affected zone. To avoid this, the carbon(C) level can be reduced, resulting in the grade 316L.
