Title: reheat treating
Post by: mater on December 24, 2009, 02:45:00 PM
I made a knife and when I sharpen it, the cutting edge feels grainy. I was wondering if this was from carbon migration ive heard about on here? If so can I aneal it and retreat it?   thanks in advance  Mark

I guess nobody is jumping on the answer to this question because there are just so many unknowns about the heat treating practices you used in the first place, the materials concerned, the condition the steel is in now, etc.

Well let me assume I got the metal to hot for heat treating. If so, can I heat soak it for awhile and get the grain back to where it needs to be and treat it again.  I may be in over my head and thats ok, Ill still learn something from all this. thanks guys  Mark

If the grain is to large, you will want to anneal the steel.  Triple normalize, then harden the steel. Then double / triple temper at the specific temperature for the type of steel.

Essentially if the blade came out wrong you need to start over at the annealing step to get the blade up to snuff.

I think that you need to post the type of steel and hardening / tempering process you used on it before the bladesmiths or master smiths that post here can give the help you are looking for.

What do you mean by "feels grainy"? What kind of stone is it?

If you do have to go back and for a redo, just follow what Ragnarok outlines above. If you want to, just get it started and holler back here.

Some things to know:

what steel is it?
heat source?
methods? pictures?

Sorry to hear that mater. I hope no one's hurt.

When you get up and running, just holler. Lin
