OK I see catagory D, I had stopped at catagory C when I saw my material listed.
But be careful because A913-65 in order to be a catagory D must have a welding process of "SMAW, SAW,GMAW, and FCAW w/ electrodes capable of depositing weld metal with a maximum diffusible hrdorgen content of 8ml/100g (H8)".
So if my filler metal doesn't meet that requirement, it doesn't meet the requirements of catagory D, so I would then have to call it a catagory C and use those preheats listed.
(which now that I looked up my filler wire does meet the catagory D, so your right, my preheat would be 32 minimum)
