Time from quench to temper?

[Nathan the Machinist]

The guy to run your questions by would be Roman Landes, if you could get Roman to talk nice about D2.

He doesn't hide his distaste for the nasty chunky carbide littered steel that I love so much.

I like Roman. He adds a lot to your forum. And his views on HT are even more extreme than my own. Makes me think I'm not too far out of wack. He has been clear on his take on high alloy air quench steels like this. He went into some detail about them last fall. Not only would he have you go directly into cryo after quench. He'd probably have you oil quench it. And then water quench out of temper. And then cryo again. Roman Landes fears no cracks!

I have been forming some questions for him, but I'm not ready with them yet.

For sure! The guy would go for a 125 Rockwell C if he could get it. The only thing more fun than talking heat treat with Roman is spending a few days fishing and drinking beer with the "Bavarian barbarian". I sincerely believe that knifemakers in the United States will always be two steps behind so long as Roman's book is not in English. That text has no equal in our literature and I consider myself extremely fortunate to have had my signed copy translated by the author.

U.S. smiths have no idea of the richness of information some of our foreign counterparts can offer, I am fortunate to be able to call Roman a friend in the knifemaking business, but I am doubly blessed to also have a good friend in Peter Johnson from the sword scene. It is really wonderful when your passion takes you far enough to connect not just with the best in your country but with the best around the world. Sometimes I really love what I do. :thumbup:
