Just to clarify... More alloying elements require more carbon for hardness... as some alloying elements hold onto carbon better

Chromium does increase hardenability... but you only need .7% carbon to get to 65-68 right after the quench... the alloying elements will tend to make that more... i think...

But with strongly...

IF you do a heat treat that minimizes retained austinite... you can get a good solid 59 apparently...

And now that i think about it becut has the same amount of carbon as aebl et al so would also not have large carbides...

Oh yes 440a and 420 hc has the same tiny carbides... but to get it hard enough to be useful requires huge amounts of care to reduce ra...

Larger carbides does occur with overheating, but primarily the chemistry (available carbon and other carbide formers) makes the size and the hardness of the carbides. PM just tends to make the...

Thats why i am uncertain whether carbide tearout is such an issue if people make cpm154 razors and they work fine...

Appreciated... but you are dealing with cpm154m which has larger carbides which some people knowledgeable people believe go blunt by carbide tearout. Carbide tearout for most large carbide steels...

The toughness at higher hardness will make for better edge stability at steeper angles. So potentially you could have a sharper razor... if the carbide volume was lower...

Becut has more niobium and less carbon... if you quench it faster i suspect it will get harder than bestar sheets... only reason for concern with all these are retained austinite after overheating...

P.s. bestar makes their own steel with niobium called be-cut... and that is available in single sheets and a variety of thicknesses. It is not the same as niolox, but knowing bestar it would be quite...

There's a few makers in America using it and here in south africa i can get what is sold as 14c28n in up 3.2 and 4mm... there are rumours about provenance... but some people get it to behave as it...

If one follows Roman Landes and Paul Verhoeven's arguments then you need small carbides for edge retention at fine edge angles. This means low enough carbon to reduce carbide size and enough carbon...
