rod failure
(OP)
OK all you metallurgical wizards....attached are the two mating halves of a rod that failed. One half has scale and the other is clean. The rod broke in transit and travelled under identical environmental conditions in the same carton.
Material is 1045 steel that was nitrided, machined, then salt bath nitrided for the second treatment (QPQ process).
It this possibly a mill issue that was exposed via the nitriding process?
Thanks for your help!

RE: rod failure
Have you checked the properties? case depth?
I would be more suspicious of either improper machining or treatment.

Here's a close-up. Would corrosion appear shiny? I've never viewed it this close.
