Never mind what I "think". Send me a chunk of this stuff and I'll grind it into a knife, and grind another knife to the same dimensions out of CPM-3V. I'll have them both heat-treated at my expense to Rockwell 58 or 60 or 62 (your choice) on the C scale. We'll pass them around have them beaten and tested for toughness, hardness, and edge-holding, in anything resembling what handheld knives are used for. Including chopping 2x4's and slicing tomatoes.
If my 3V blade loses in any way, I'll pay for the test steel and personally cook and serve you lunch in my home. If my 3V blade wins in every category, you owe me a coupon for a Happy Meal at McDonalds or a dollar-menu item at Wendy's or Taco Bell... Fair enough?
In the name of science, I'd be happy to buy you some steel to work and experiment with. I'll call up Carpenter and see what it'll cost per a sample, I had read that AerMet 100 can be purchased in very small lots, not sure about AerMet 340, I'll find out on Monday.
From Carpenter's website.
Forging
"Primary breakdown forging of AerMet 340 alloy should be done at a maximum starting temperature of 2250°F (1232°C). Finish forging should be done from 1800°F (982°C) with a finishing temperature below 1650°F (899°C) in order to optimize the final heat treated properties. Following forging, the parts should be air cooled to room temperature and then annealed. Following the anneal, the forgings should be normalized in order to restore properties to the dead zone. "
Is this something that your level of expertise can handle if I bought and sent you some?
James - I volunteer for the testing.

TLC: James does not forge the steel to shape - he grinds it, so if you buy a piece of bar stock, say something in the area of .25"x1.5"x18" he can very adequately shape it and the HT service he uses has all the expertise needed to bring out the best AerMet has to offer. Using the outside HT service also removes any argument anyone might have of bias in the HT, because they would have nothing to gain by providing anything less than their standard of excellence on either steel. Same with James' offer - he has no relationship with Busse, and he is all about trying new steels to see what they can do.
