How to Thermal Cycle Knife Steel
Thanks to Jake Smith, Erik Mittag-Leffler, Ashley Wagner, David W. Debora Richards, gspam1, James Straub, Tim Ottawa, Flynn Sharp Knives, David Millington, Joseph Baier, Alex Roy, and Noah for becoming Knife Steel Nerds Patreon supporters! These experiments are very expensive and time consuming so your support is always appreciated.
How to Use a Steel Datasheet to Develop a Heat Treatment
Thanks to David Reem, Colton, camilo, Brendan Gildea, Vince Koacz, Monery Custom Cutlery, Curt E, Shannon Sanders, Brazilian Blades, Rory Kelly, Brunhard, Zachary Chumley, Noel, Adam Nolte, Gundam lupus, and Jan Huch for becoming Knife Steel Nerds Patreon supporters! I still don’t know when it will be time for the announcement of my new steel so until then you can get all of the data on its properties exclusively on Patreon.

I was interviewed by Shawn Houston on his Youtube channel about the micrographs article. See the video here.

Why Anneal?
There are three primary goals of annealing steel:
- Make the steel machinable so that it can be easily cut, drilled, and ground.
- Setup the steel for austenitizing and quenching (hardening) so that is has good heat treating response
- Provide the best possible properties in the final heat treated product
The above goals are not always 100% compatible, but we would like to offer the optimal combination based on our priorities. However, to know what the trade-offs are we need to know how annealing works first.
Cru Forge V – Toughness testing, Processing, and Background
Cru Forge V was developed by Crucible for those who forge their steel for knives [1]. It was developed shortly before Crucible’s bankruptcy and is reported to have been tested with the help of knifemakers Howard Clark and Dan Farr and that the code name prior to its official name was 1086V [2]. The steel is not listed anywhere on Crucible’s website and does not appear to be in production any longer, but as of March 2018 is still available from some third party steel sellers [3][4][5]. The steel has the following composition [1]:
What is the best temperature for L6 family?
Annealing?
Heat Treat?
Tempur?
There are recommended normalizing, annealing, austenitizing, and tempering temperatures for L6 in the book Knife Engineering.
