What's the difference between annealing and tempering? Are they the two ways to say the same thing? When I looked up the definitions, they both said it will soften the metal that will be worked.
So tempering is what the file needs. Got it. A shopping I will go....for a heat treat oven.
Is there a chart or book that has the formula for different types of steel?
I'm new here. I saw a video on making knives from files. What temp do you "cook 'em" at and for how long to soften them up? Obviously a dedicated heat treat oven would be best but at this point cash is not flowing freely. The kitchen oven might have to do for now. Any help would be appreciated.
