How To Temper Steel For A Knife. Hardening it brings it up to a very hard state, but in this state the blade is too brittle. Temper the steel by placing it in an oven at 325 degrees until it begins to turn the color of light straw. You will need a pretty good torch or some way to direct the heat, about 1500 f, you can heat directly with a oxy aclyene torch. When we talk about hardening knife steel, there are two principal processes to consider.

There is a point of diminishing returns, however. The actual temperature of the steel depends on the carbon content inside. You will need a pretty good torch or some way to direct the heat, about 1500 f, you can heat directly with a oxy aclyene torch. The following seven steps show how to use heat treatment to harden and temper your knife. You have to harden it first and you have to temper it second. Watch for the color of the steel to change as it gets hotter.

The actual temperature of the steel depends on the carbon content inside. These alloys are more formally called steel. As for how to harden a knife blade, you need to heat it to a red hot temperature. By first heating the knife steel to between 1050 and 1090°c (1922 and 1994°f) and then quickly cooling (quenching) it, the knife steel will become much harder, but also more brittle. Dipping the blade in motor oil makes it harder but also more brittle, which is why it’s important to temper the blade afterward. Without any further ado, let�s get started.
