I've seen it on a good bit of 440C and seen it quite often on D2 when taking it to a mirror finish.
The cleanest 440C and ATS 34 I've worked with was from R. W. Wilson but he doesn't have any more of the 440C. At least not in the sizes I use.
RW and I discussed this once and he told me that steel was Hitachi and was rolled in bar stock. He told me one time you will see more of that cloudiness in the plate steels but don't know if that has to do with the way it is rolled or just the mill it came from. The steel we were getting from Hitachi was in bars where as most other suppliers I've gotten it from you can tell it's been sheared from a wider plate.
RW was checking on another mill run of that from Hitachi but the price they gave him was as much or more than the CPM and CTS steels so I'm leaning in that direction for the future.
Hopefully Carpenter is doing as good of job on the CTS batches they are making for Scott Devanna as the samples they have sent me. If so the CTS-40CP is the way to go if you want some clean 440C. It is 440C powdered steel.
I can't decide if I like it or the XHP better.
I don't think you will see this in the powdered steels because of how it's made.
