The 4130 doesn't appear much different at all from the other alloys. The composition of the build up is primarily un-oxidized 4130. I'm working on compiling all the data I have and looking at all possible parameters.
I'm really just looking for a direction to head with my research on this...
I've talked more with the rolling operator, and it seems the build up we're struggling with happens occasionally on other grades of steel, but almost always on 4130, which is why they associate 4130 with the problem. This speaks to your explanation pretty well.
However, x-ray compositional...
Thanks for the help, and I think that's a pretty viable explanation, but I'm still struggling with why this would be an issue for ONLY 4130, and not any other grades.
Hello All,
I'm having a problem with some 4130 steel accumulating on a high-carbon, high-chrome, high-nickel (don't know exact concentration) stainless steel guide foot during rolling. The stainless steel is at about 300 F (due to ambient temperature) and the 4130 steel is at about 2250 F...
