My Tool Steel arrived during the week overnight from Adelaide no less! I have ordered 2.0 mm and 1/16th ground stock to test out some blanking die ideas.
The 2.0 mm needs to be heat-treated. Actually they both need heat treatment to be used as pancake dies, but the 2.0 mm is going to be wire cut (EDM) which means that it can be hardened prior to wire cutting. It will be a good idea to drill the hole for the wire before hardening!
To help in the heat treatment process I have taken a tip from the knife makers and ordered some heat treatment foil. It’s coming from AKC's Knifemaking Supplies in Perth, Western Australia. Ticronic steel foil is for scale free heat-treating without special packing or atmospheric controls. The foil is Titanium bearing chrome nickel steel and is recommended for temperature up to 2000 degrees F. It is .002" thick.
