Section II Part D Table 1A Note G12

[heatexguy]

SA-240 Gr. 316 Max. Temperature Limit for Sect VIII Div. 1 is 1500 F. Note G12: above 1000 F these stress values apply only when the carbon content is 0.04% or greater. I take this to mean you can't use this material above 1000 F if the carbon content is less than 0.04% carbon, because you have no stress value to use. Thoughts on this?

Correct in your interpretation.

Thanks metengr! B16.5 is more specific with the limitation.
