M390 Steel – History and Properties (and 20CV and 204P)

[Larrin]

New article about M390 steel, which has a surprisingly convoluted history in knives. The steel was released prior to many other powder metallurgy stainless steels, but was never used in knives to any great extent until a couple decades later. I also summarized its properties including microstructure, edge retention, toughness, corrosion resistance, etc. https://knifesteelnerds.com/2020/06/01/m390-steel-history-and-properties-and-20cv-and-204p/

Thanks for another great write up Larrin. M390/20CV is one of my favorite stainless steels.
