Micrographs of Niolox, CPM-154, and AEB-L
Update: 1/6/2020: I have taken micrographs of many more steels which you can see here.
Recently I had samples of Niolox, CPM-154, and AEB-L analyzed with SEM. Vilella’s reagant was used which is common for tool steels and martensitic stainless steels because it etches the martensite matrix so it is dark and leaves the carbides bright. The compositions for the three steels:
3v Modified – The Lost Crucible Steel
I enjoy reading patents from steel companies, it reveals information about new products and research often not available otherwise. One thing I’m surprised there isn’t more talk about is a steel Crucible patented but never sold – an improved 3V: https://www.google.com/patents/US7615123
Thanks for what you are doing. There is so much misinformation, hyperbole, and exaggeration being presented as fact on the internet regarding knife blade steel. I felt like the skies cleared when I discovered your site. I really appreciate your science-based approach to demystify so many issues.
Thanks!
Can you tell me about AR-RPM9 please?
Thanks,

I’ve only written about AR-RPM9 in an article exclusive to the Knife Steel Nerds Patreon.
