I am trying to do a % austenite/ferrite count on a weld crossection of 2205. NACE MR0175 requres the count per ASTM E562. I have the standard, but have never used it before. It seems like it would be really difficult to do in the weld considering the microstructure. Has anyone followed the ASTM standard that could give me some pointers. Is there another acceptable way or some reference material that could be suggested. I ran my ferrite gage across the crossection and get acceptable results, however, I would like to meet the ASTM spec if possible.
