Here is a list of alloys that are currently available for corrosion rate calculations. Also listed is whether or not the alloy is suitable for the thermal aging calculations.
All compositions are in weight percent.

Notes:
Note 1 = Alloy 625 can contain up to 3 weight percent Niobium which alters the mechanism for thermal aging. Thus the thermal aging calculation is not available for this alloy.
Note 2 = the composition for this alloy does not enter into the corrosion rate calculations in the OLI software. The compositions listed are maximum values for each component and may or may not sum to 100 %. They are included here as a guide.
