You can. You will get a smooth lamination line without the forging marks.Can you just HT at full thickness? Is there issues with this material just doing a HT and then shaping?

I've got two pieces at Peters' right now with this strategy. Hopefully I'll get them back soon and see how it works out.You can. You will get a smooth lamination line without the forging marks.
Sold out I believeI also don’t see it on the website. Am I blind?

Sounds like a good alternative to the relatively difficult to obtain Japanese laminated steel.
how you quench this to avoid crack in core ?26c3, I like, mix it with 304 or 410, works great

Same question , how you quench this san-mai to avoid crack in core ? Edge quench ?I have some
I forged out three knives and here’s one of them I completed and I’m grinding a big Gyuto today
I handled the material just like I do the Hitachi laminated steel i get
I forged it out, annealed it in vermiculite, cold forged it, thin slip layer clay coated it and heat treated by Eye in a Forge and quenched it in straight water
The only thing I noticed is that the 26c3 Core material was thinner than what I’m used to (percentage of the total thickness) but so far it hasn’t appeared to be a problem
it’s possible that I feel like it was a little harder to Forge maybe because the stainless was thicker... not certain about this

That is stainless san mai ? I mean carbon steel core and 410/304...etc stainless on sides ?or you can quench in straight water
yes, correct, 410 ssThat is stainless san mai ? I mean carbon steel core and 410/304...etc stainless on sides ?
We’ve been working on the san mai for more than a year. We planned to release the material in a few weeks but Murphy got in the way. A billet must be visible on the website to be added to an order. Jessica made a billet visible and it sold before she could add it.
The billets are made on our 1,000 ton press. In our testing, we've been happy with the weld strength. All the billets are flat ground after forge welding. A few knifemakers have tested the steel and we’ve received excellent feedback from them.
Jon Walker does all the forging in the shop. He has some great ideas for future san mai projects.
We are currently sold out, but we will be adding more billets to the website this week. The core material of the billet determines the web page i.e, 410 / 26C3 will be on the 26C3 page, 410 / 52100 will be on the 52100 page, etc. We plan to use different alloys for the core. Let us know if you have a preference for the core alloy.
