I was interviewed by Shawn Houston on his Youtube channel about the micrographs article. See the video here.
Background
How Annealing of Steel Works – Subcritical vs Transformation Annealing
Thanks to Larry Corsa and Gene Kimmi for becoming Knife Steel Nerds Patreon supporters!
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.

Thanks to Kenneth Pinnow for talking to me about 3V steel development, Gary Maddock for talking to me about PD#1, CD#1, PD#5, Z-Wear, and Z-Tuff, and Mark Zalesky and Clay Aalders for getting me a scan of a 1979 Knife World article about Vasco Wear.
