Sanmei Steel by the piece!

Aldo,

The thinner the core the better for kitchen knives, as you can see it is easy to grind into the cladding. .35-50 would be optimal, if it is possible.

Random steel choices won't work well. There has to be some consideration of how the steels will react during heat treat and quench.
 
Count me as definitely interested! Mainly 52100 and Blue. Excited to see these roll out in the future.
 
Dang... man...

I've been working on supplying this very thing with my cohort... We had been noticing a demand with no real steady supply.... We've been getting good results with a rolling mill, and at about the same final sizes. But we have been very simple so far with 416 or 420 over 1095, etc... Those combos you're talking about make me drool. Do you planon just rolling/hammering flat and sending it or are you using any dies to put some figure in the billet?

So I guess at least that means I think it's a good idea! I'm sure you could kill us in the final price area. And I'm sure you'll tick off a few makers who use the laminates as their milieu... I'm sure it will be a winner Aldo.

Cheers.

I hope you left off a zero. Did you mean .035.050" ?

Exactly what I thought when Aldo brought up M4 with stainless cladding. Like I said...that would be my choice...but I don't have the forging experience to tell you if M4 would bond well with stainless. I hope it does. As Butthead would say....."Yeah...heh heh....that would be cool...heh heh".
 
This is a sample of the 420/1095 SanMai that we welded up this weekend. We were also able to successfully weld the 52100. (Pics to follow)

I know some of you are waiting with baited breath on the 3V and M4. We just couldn't get to it.

The core on this sample is about .070. The overall thickness is about .200(3/16" oversized). We should have no problem making a thinner core for kitchen knives. At the moment we should be able to supply 2" x 12" pieces. We are working toward making larger dies for the process that we are hoping should yield us 3 or 4 x 24-30. That is going to take a little time to get together.

Regards,
Aldo Bruno

Aldo will probably post the availability when it is ready. Cost will be on his website...and is best left out of Shop talk.
 
Hey Guy's,

Here is another sample of what we are trying to do. This is 1095 with a 410 skin. We decided 410 will probably work out the best for us.What are your thoughts?

I was really hoping for a martensitic outer layer over a high-hardness core.

I like that a lot. A good core metal and it looks like a good core thickness.\

Personally, I don't care if the skin is martensitic or not. Hardness isn't an issue, since it won't be cutting anything. It is there for corrosion protection and looks.
 
Stacy, We are finding that the 410, in spite of not hitting heat treating temps, stiffens up better then the 300 series and offers just enough carbon to help with the welding.
