Anyone have a rough estimate of what an expected core hardness would be of a 3/8" section 5120 or 5120H steel carburized then quenched and held at 480-500 F? Tried an online search but couldn't find good info. Thanks in adavnce.
I've tried a search on the internet and do not have access to any technical manuals (I'm away on business). Does anyone know where I can find technical data on semi-processed electrical steel BEFORE the quality anneal? The material is specifically 26M47. I emphasize the 'before' because there...

I am looking for a study with supporting data that compares heat treat results between nitrogen-methanol systems vs. endo-gas atmospheres. Other than operating cost advantages/disadvantages, is there a process control benefit to one system over the other? I appreciate anyone with experience...
What are the principle causes of retained austenite of Q&T steel and what are the normal process adjustments that can be made to eliminate it?
Thank you in advance.
I am interested in a standard process for the carburizing and oil quenching of a thin section steel (10B21). The part is a pinion with section sizes varying from 2.1mm to 4mm. Other than part geometry, what else can be done to avoid cracking in the quench? Thanks in advance for any information.
I am interested in possible solutions to soft spots that appear after a vacuum-nitriding process. What types of chemical or pre-treatments should be considered and/or avoided? What are other process failure modes that could cause soft spot? Assume that the base metal is within spec before...
