316L St/St is a low carbon stainless steel containing approx. 18%Cr and 8%Ni with 2 - 3%Mo for added pitting resistance. As such it is a good all round choice.

You say application is highly corrosive; if you mean from sea salt conditions only, I think 316L will be fine. Try to achieve as good a surface finish as possible to reduce likelihood of corrosion initiating.

If application is highly corrosive from moist acidic atmosphere for instance, then you might consider a Monel 400 or 500 Nickel alloy.
