Topic tags/keywords: chinese steel heat treating annealing

It seems like I ended up with a bunch of chisels that were made in China. These are turning chisels and wood chisels. Other than sharpening them daily has anyone tried to heat treat these? I have successfully heat treated and annealed a few objects in my lifetime but have yet to try it on Chinese steel.

Anybody?

I’ll be sipping my coffee hoping for a reply. Thanks,

I haven’t try that on chisels, but about a couple of years ago, at my work, we use many high precision tools, like micrometers, calipers and indicators, I was trying to make a customize tool with a micrometer head that would have a precision of at least .001” but I was actually looking for .0005”. A friend told me to head up the base of the tool (not the micrometer head but the base where the mic was going to be sucure) with a gas torch until it was red hot and keep it like that for about 5 minutes, after that I diped the tool on a bucket of used car oil to cooled down.

After that I took it to another friend that owns a surface grinder so that I could have a totally flat surface to achieve those .0005”. it really came out nice if I can find it I will post a pic.

Hope this little story helps
