What effect does spot heating do to steel

Recommended Posts

Posted (edited)

Reason for question... I want to be able to stamp initials into my blades.  I  really didn't want to stamp before heat treatment because of all the sanding afterwards.  Can you spot heat the area  with a pin point flame where you want to stamp? Thinking it would be a lot less clean up, plus saving the stamp. How would it effect the heat treatment if done in a small area? What else am I missing? Pic is another little finger knife I made in progress...with my initials stamped after heat treatment.  Not best practice. 

Thanks again... David

Heat transfer.  You won't be able to use a flame to heat just that area for stamping.  Even if you kept the blade in water while heating then it would start spreading to the blade when you pulled it out to hot stamp it.  Now, you could slowly cool it with a torch while the blade is still in water to temper, or even 'quasi-normalize', that area for cold stamping.  You could also keep from hardening there in the first place if you wanted to.
