    Hey guys this weekend I'm gonna finally get my forge up and running. I was just wondering if anyone could direct me to a list of steel types and temps and soak time for heat treating.

    This temperature color guide is used to identify the approximate temperature in degrees Fahrenheit of steel at different temperatures. The left side of the color guide is generally used to identify the temperature of the steel during the austenizing phase of the heat treating process, or during the forging process. The right side of the temperature color guide is used to determine the temperature of the steel during the tempering phase of the heat treating process, or during operation.

    The chart John posted is really good to have, but keep in mind that the colours will look different in your situation (outside vs inside, shop lighting, etc.)

    If you start with a nice forgiving steel like 1084, your best friend is a magnet. As the blade gets red, start touching a magnet to it. When the blade hits non-magnetic, you're ready to quench. It's important to catch the non-magnetic state as the blade heats up. You don't want to overshoot.

    Good points to be added, sometimes I gloss over the little bits.
