If the items were just tacked together there would be small localised hot spots which would be quenched by the adjacent comparatively large mass of cold steel hence the hardness associated with the weld. This phenomenon is what causes the cracks when welding high carbon steels. |

Hi Stew Just been having a sort out of my material stash and found this stuff .The writing on the wrapper says that it is KE672 -AISI 01 type oil hardening alloy tool steel analysis as follows. Carbon 0.95% Manganese 1.20% Chrome 0.50% Tungsten 0.50% Vanadium 0.50% I have 2 bits 0ne is 20x8x500 other is 16x10x500 if you are still stuck for some tool steel i could cut you a bit off one of these .Seems pretty tough stuff to me. Cheers Paul |
