Last week while I was in AL I had the pleasure of meeting Allen Faulkner. Allen hquit making knives about twenty years ago and had soMe 0-6 leftover. I bought a piece off of him that is1/4"x1 1/2"x30". He said that I would like it better but never would really give me a reason why.What is the difference andif I like it where wouldvI find it . Nobody seems to carry it.
 
06 has graphite in it to make it easer to machine. the graphite is Free graphite in the microstructure meaning that it is little chunks of graphite mixed in to allow easier machining as the graphite acts as a lubricator. I have heard that it is not as good as 01. now what is as good and is very hard to find is O2. Its really O1 without the chromium so it welds a lot better in Damascus steel.
 
I don't recommend free machining steels for blades because of the inherent brittle nature. When I worked for Timken who developed graphitic steels there were those who made knives of it but I don't know of any serious knives that were made from it.

is there a temp and soak time that could be used to dissolve the graphite. I have always wondered this.

In essence you would have to melt it, upon solidification you would find that you have cast iron

BTW, I believe you can turn on a spellchecker in your BF settings, It would make your posts a whole lot easier to *rheadde*:eek:

Graphite ,not carbide is the equilibrium condition of carbon in steel.Normally we never see equilibrium but in the case of the graphitic tool steels we add more silicon to change some of the carbon into graphite. I spent a lot of time with them and they are excellent tool steels.
 
So is it good,bad,or ugly? Either way I plan on using it toake my version of a Randall#1. I'll let you know how it turns out.

Heres the breakdown carbon 1.45%,manganes 0.80%,silicon1.00%,chromium0.20%,molybdenum0.24%,and graphite 0.45%. The only problem I think I'm gonna have is finding it if I like it.

With that much carbon and chromium you are going to want to kiln soak it forever to get the non-graphite carbon and chromium into play, not a forge HT in my opinion

man it seams like i have been getting a lot of crap for my spelling lately, more then normal. o well i guess, i have been trying to get better at it.

I have William E Brysons book on heat-treating and steel selection and it says a1200 degree presoal for 15 minutes then proceed as usual for for 0-1.
