LC200N/Cronidur 30 – History and Properties

[Larrin]

New article about LC200N/Cronidur 30/N360/Z-Finit, a steel developed in the early 90s for high corrosion resistance from a nitrogen addition. I summarize the development of the steel, and properties we have measured such as hardness, corrosion resistance, toughness, and edge retention. https://knifesteelnerds.com/2021/06/28/lc200n-cronidur-30-history-and-properties/

Great article, Sir Larrin! I really love LC200N. Edge holding is good enough for me and it’s really easy to sharpen, which is great for people like me who are bad at sharpening. I appreciate the toughness, and I seem to be able to rust most stainless steels in the humid summer, so I’m mostly carrying LC200N these days. I suspect it will eventually be supplanted by MagnaCut, and I look forward to that!

Excellent read, as always very interesting, thank you!

Awesome article as always.

Lc200n is one of my favorites living in FL.

Thank you, Dr. Larrin. Great article and very readable for us non-metallurgists.

I would be interested to see what you can design that would have the toughness and corrosion resistance of LC200N, yet have the edge retention of S90V or something.

(As a side note, I am constantly flabbergasted by the toughness of 420HC!).
