  18. How to heat treat 4140 - The Home Machinist!

    It all makes sense now. I heat treated a piece of, what I thought was, A-6 tool steel. The piece did not machine like tool steel but I have never worked with A-6 tool steel. Now I think the piece was actually 4140 because after tempering at 600 deg, the piece lost most but not all of the hardness. Tempering 4140 at 600 deg makes 4140 49 RC.
