Hey Folks,

Well, it seems 1084 can't be found for love nor money. Is that so? I know Aldo will have some hefty stuff (.25" x 1.5") later this summer, but that's then. Anyway, I would prefer 1" wide stock.

But, right now I'm looking for stock to forge up with 15n20, so more like 1/8" thick would be better. Still can't find any though. I talked with Kelly Cupples, but all he has is 1080. He was explaining to me 1084's and 1080's alloy spec ranges actually overlap. I understand that 1080 HTs exactly the same as 1084.

Any comments?

Thanks, Phil
 
Just about the only reason I can think of that there is 1084 is to compensate for 4-5% of carbon lost during forging so you end up with 1080 instead of 1075. Either way your blade will still hold a mean edge.

Farmer Phil,
Sheffield supply has 1084 1/8" x 1 1/4 and 3/16" x 1' in their catalog. I haven't ordered any yet to confirm it is in stock but it is in their catalog. They also have 1080 1/8" x 1 1/2" and 3/16" x 1 1/2" and 15n20 .049 x 1 1/2" . For material orders only 1-800-874-7007 . For information and catalogs 1-386-775-6453.

Hope this helps and great question !

Take a look at the specs and decide for yourself :)

You shouldn't notice a difference. That said, you will likely notice a difference in etching if you compare to Aldo's 1084. His tends to be on the high side of the spec for Mn which means it etches darker.

1084 was a standard steel for many years - it's not got extra carbon for forging, as far as I know, it just got "picked up" by the industry. There are all sorts of specs for 10xx series steels, going up in .4 -.5% incremements in most cases.

1080 should be a fine replacement for 1084 in your application.
 
I got 40 feet of that stuff delivered for about $80. I still have about 37 feet left

Well that's not to bad go mike, I ordered 35 feet a couple weeks ago and it arrived today - $140 delivered up here to Canada!
 
To answer you question Phil, 1080 would be a fine steel to use. 1080 and 15n20 is what Ed Caffery uses in his damacus.
 
1084 is the eutectoid, and has the easiest HT. 1080 is basically the same thing. They are interchangeable as far as knife making.

Thanks for all your input guys.

That special at Admiral sounds pretty good. But, I'll have to see what the total will be with the shipping. Kelly will throw in the shipping and cutting if I order over $100. So even though his per pound rate for his 1080 is higher, it's conceivable the total could be comparable. I would rather give him my business too, but then I've also got it in my head to use 1084. I'll keep you posted.

All the best, Phil
