One of the remarkable features of these tool steels is the low draw temperature to achieve maximum torsion impact strength. Most drawing can be done in a kitchen oven! Or you can easily make a small and efficient draw furnace on your bench using furnace brick, a simple heat element and a kitchen oven heat control.
