So the steel supplier accidentally sent me ABL Stainless instead of 15n20. I looked online for a bit and in the heat treat app and I couldn't find anything in regards to it. I might have misheard him, but replaying the message it sounds an awful lot like ABL Stainless. Can anyone help shed some light on this?

try researching perhaps AEB-L ???

 

Thanks Steve, that seems much more accurate. It also seems like a much more complex steel and heat treat than I am ready for, unfortunately.

AEB-L creates a very nice edge due to its chemistry being designed for a lack of large carbide formation, assuming a correct heat treat of course. Its a great stainless to work with, IMO. Lots of bladesmiths recommend it for razors.
