AISI 316L AISI 316 Ti selection help
(OP)
What's the difference betwheen 316L and 316Ti in tubes 18mmx 1mm in contact with CH4 smoke ? at 450°C
and with condensate (PH 2-3) at 120°C

The suffix L denotes low carbon, the suffix Ti denotes addition of Titanium. These modifications are useful for avoiding sensitization, that is precipitation of Chromium carbides along grain boundaries while welding, a condition prone to intergranular corrosion attack.
The modifications do not change the relative resistance to corrosion attack of the base material.
Producers might suggest other materials like Duplex stainless steels, capable of similar or better corrosion resistance in the specified environments.
