I have some 3/16" 416 SS I want to use to make a laminate with some 1/8" 1080. My understanding is that with these stainless laminates, you want your billet to be about as close to finished thickness and length as possible to minimize drawing out. But I'm going to be starting with a fairly thick billet with what I have to work with. I have a 24.5 Ton press.. but I'm not sure how even that will handle bringing that 416 down.... So would I be better off grinding my 416 down???
 
I use 3/16 416 And 3/16 52100 all for my san Mai. I start with six inch long by 1.25 wide pieces.I weld and draw out under a 50lb little giant hammer. from the stack of three I draw the billet to about .110 thick by 3 inches wide by about 14 inches long. the only problem I have run into by drawing too far is carbon migrating from the core into the stainless and the core not having enough to harden properly.this seems to happen at a core thickness of about .045-.060 depends on heat and time at temp.
 
Wow that was nice of you Bill I was just think of trying this and thought I heard you need three equal piece's.
 
No problem Brett, Just remember to keep Shrek and that little mexican out of the Ivory until I get there.
 
thank you very, very much.... first I've heard of keeping every layer equal.. so that helps quite a bit. Hopefully my press can beat it down the way your hammer does....
 
Why use 416? What does 416 give you that a high carbon stainless would not? I really envy you guys that get to smash hot steel together.
 
Thanks Bill. I heard mention of this problem with the carbon migration and was going to try it with a thin piece of 15N-20 under the stainless (technically making it five layers.) I was thinking that a .20" piece of the 15N-20 would be have enough Nickel to prevent the migration and it would allow you to use a thinner 52100 core. Even a slice of pure Ni foil might work too. What do you think of that? I have not tried it yet, so don't have any data on it.

Mike, I have not tried the 15n20 to know if it will work or not I do know the nickle foil will work for preventing carbon migration. I like M.Q. like the look that I get from the migration zone so am just learning how and what I can do to control migration.
 
Very good. I forgot about that hazy effect from the migration. So, would that also answer the earlier question about using high-carbon stainless instead of 416? Do you think there wouldn't be as nice of an effect if you used, say 440C or something?

One problem that I can see using high carbon stainless is that it will get nowhere near austinitizing temp during hardning so therefor will not be stainless.
 
416 is a high sulfur free machining grade of 410. There should be some limitations in forging it because of the sulfur.
