Thread: Best Stainless for Razors ?

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 start to happen at about 15deg per side... so if you can lessen that you might get a nore stable edge... This will be lessened by a tougher matrix, but mostly smaller carbides...


So yes this is theoretically speaking, and i wouldnt suggest any of the large carbide steels for razors....

Razor bevel angles are 15 to 20 degrees inclusive, or 7.5 to 10 degrees per side.

Please expand a little more. I thought the point of crucible particle metallurgical steels (CPM) was to have the smallest carbides possible at manufacture. How does that translate into larger carbides, then tougher and smaller? It's confusing the way your statement reads, to me anyway.

Larger carbides usually occur because of overheating. Maybe I missed something.
