1095 Tempering

[rufnekjr]

Hello all, I'm a beginner bladesmith and I'd like to ask if anyone has the tempering specs for 1095? I want to put together or find a cheat sheet that can tell me what temp and time to temper that steel. Also, can you use a propane forge to heat the steel for tempering? I do not own an oven that I trust to not burn my house down while tempering.

It depends what your intended usage is, and what hardness you are looking for. Going to need some more information. You can simply google a 1095 tempering chart for hrc values.

Plenty of heat treating info in the Shop Talk section of the forums.

Welcome Rufnekjr. Fill out your profile so we know where you live and a bit about you.

For a knife blade, 1095 tempers between 350°F/175°C to 450°F/230°C
I use 400°F/200°C for most blades.
Larrin's book "Knife Engineering" is an invaluable tool for getting really good results in HT.

Larrin's HT regimen for 1095 is:
Heat to 1425-1475°F and hold for 10 minutes. (HT oven is the best way to do this)
Quench in fast oil. (Thick blades can be quenched in brine)
Temper twice for one hour each cycle at 350-425¯F.
