I have an order of a large camp knife, 15" overall lenght. I wish to use A2, 1084 or 5160 for this one but I couldn't find any usable size stock for these steels in Turkey. I don't want to import some steel in order to make only one order. All I have is D2, RWL34 and K510...

I was thinking to forge this order out of Bohler K510. It is a silversteel grade : specs are here : http://www.sten.fi/english/data/attachments/K510DE.pdf
My stock is 1" dia rod...
Do you think it is tough enough for a large chopper ?. I only made some small knives and it has good edge holding and polishes real fine...

Is it a shallow hardening steel to produce hamon, or with some Cr 0.7 and V 0.1 it is a deep hardening one? The soak time is about 30 mins so I'm guessing it is a deep hardening, but I'm not 100% sure...

Thanks...
 
I'm far from an expert, and hopefully one of the many experts here will chime in but, it sounds close to O1 which will make a fine chopper if tempered between 56 and 60 rockwell.Judging by the alloys I would say its a deep hardening steel like O1 but wiser minds may disagree.I don't know how you go for size availability in Turkey but Bohler also do versions of L6, and 5160 here in Australia.It sounds like the best choice from what you have available,go with a slightly lower rockwell and make sure your thickness and edge geometry are suitable and you should be right mate.
 
Emre that steel will work fine. Shoot for 57-58RC temper. as well I'm not certain I that much chrome will make it deep hardening or not. It looks like it might be in the middle between O1 & W1. So we need METE!

Thanks friends, i'm hoping that it will do the job as to search for a usable size steel is damn hard work in this country.

Amen to that, bro :D I hope he will chime in and clear things up, it is horrible to forge a 1" rod to a knife and finding out that you worked for nothing :barf:
I'll start to forge this beast by Tuesday, untill that I hope some one knowledgeable about metallurgy will answer this problem...
 
Must be plenty of spring steel (5160) at your local motor car wreckers, most of them make good knives.
