This part is a cut shape from plate. The CMTR confirmed it and it also came from a mill in China so the thought on poor quality is not out of the question. The pores due exist prior to applying the developer because they were seen while maching the part. The part isn't completed yet and when...
Attached should be a picture of what I am calling "porosity" in the A36 plate.http://files.engineering.com/getfile.aspx?folder=e4a5ccc5-59cf-49f4-9da1-7c45294713e2&file=IMG_0228.jpg
I'm using the word "porosity" for this plate becuase there are actually voids or holes in the material which I would expect to see in a cast part, not rolled plate.
I am manufacturing a part from a 19" OD x 4.25" thick piece of A36 plate and while machining it, porosity was opened up. I am used to seeing this in castings but not in A36 plate. We performed a liquid penetant test on the machined surface and the porosity was visually worse. Can anyone speak...
