I tried to zip it and added game, still nothing, am I missing something?
In the Neolithic mod, chromium can be found like copper on the ground signaling the zone has some.
The initial recipe I wanted was 70% iron, 13% chromium, 15%lead and 2% copper(aka, iron+chromium+ molyb... that google said it's used in steel for getting it stronger), anyway... I just searched steel making on google, and because I can't put iron+charcoal because of alloys take metals and that would be tooo easy for gameplay sake so iron armor is useless.
I tested it again , yeah.. iron can't be smelted rn even if the steel alloy has a melting point of 1250...
