Gergely Posted January 20, 2017 Share Posted January 20, 2017 Hi All, I know that this kind of ask for help is way out there because there are thousands of alloys and who knows what might show up in a Hungarian scrapyard. Still if you could give some pointer thoughts, search criteria or anything, it would be great. So, I found a 32mm/1 1/4" dia, 2m/6' long piece of steel bar. I was told it was brought in with a bunch of 304 stainless steel rods, and also with some 420 type stock I identified pretty surely. This bar in question has shiny appearance as a round bar stock. It is normally magnetic. While spark testing it threw short bright orange sparks, there seem to be low/very low carbon in it, and nothing I could recognize as distinctive element (ie. Tungsten or Chrome). In its original state files bit it very easily. After spark testing gave me no useful information I thought I try to forge it. Under my 30kg/70lbs springhammer at orange heat it forged like butter, easier than mild steel in same size. When I gave it some taper (but no sharp point) I tried the three step harening test. First I heated it to high orange (where 420 types harden when quenching) and let it cool in open air. Next morning I ran a file on it and it air hardened so much that no file bit it, not even at the corners. Hardening is consistent at the whole surface it was heated. Non heated surface remained soft. If these infos ring a bell to anyone, please feel free to share. Or about any more testing which could provide more usable information. Also if you got some ideas what to use this material for it is welcome, too. Thank you for time and energy! Bests: Gergely Quote Link to comment Share on other sites More sharing options...
