Product Details, Specifications, and Technical Information


- The highest carbon stainless steel of the 440 series.
- It is a very good blade steel.
- I think the reason it is not more popular is because newer steels have overshadowed it.


This alloy been properly annealed and is in the soft condition. You do not have to do any non-standard wasteful processes before heat treating. The steel must be heat treated to get to a hardened state. Follow the heat treat recipe and the steel will harden.
