Heat Treating A2 Steel
I have an electric kiln that ramps up to a maximum of 1700 degrees fahrenheit. The recommended temperature for A2 austenitization is 1750 degrees. Can I adjust for the lower temperature some how in the annealing phase, and if not, will the difference in temperature significantly effect the Rockwell hardness? I am shooting for a target hardness of about 60. The blade I am working with measures 9" X 2" x 1/4". I would appreciate any advice, as this is my first experience with A2.
Thanks. |

There is no way to adjust the steel to austenitize at 1700F to the same degree that it would at 1750F. Chances are, if you heat your kiln to its maximum and let it soak for a while the temp might creep up a bit. In any case, the steel will still get hard at 1700F but the grain structure will not be as fine as desired. That means the steel will be hard but not as strong as it could be but A2 is so tough that you might never notice the difference. Still, the smart money would try hardening a piece of A2 and then break it (without tempering) to see how tough it was and how the grain looks........

Is there anyway to add a heating element to your oven? It wouldn't take much to get a 50 degree rise in temp.
